docs: fix two broken links in README (license badge, docs reference)

[cnYui]

Two links in the root README.md currently return hard 404s. This PR fixes both; the diff is two lines and touches nothing else.

1. MIT License badge (line 3)

The badge links to /tree/main/LICENSE, but the repository's only license file is LICENSE.md — there is no path named LICENSE, so the badge 404s.

-](https://github.com/visgl/react-google-maps/tree/main/LICENSE)
+](https://github.com/visgl/react-google-maps/blob/main/LICENSE.md)

This is a missing file, not a /tree/ vs /blob/ quirk — GitHub happily resolves tree paths for files that exist:

$ curl -sSL -o /dev/null -w 'final=%{url_effective} code=%{http_code} redirects=%{num_redirects}\n' \
    https://github.com/visgl/react-google-maps/tree/main/LICENSE.md
final=https://github.com/visgl/react-google-maps/blob/main/LICENSE.md code=200 redirects=1

$ for f in LICENSE LICENSE.md LICENCE license; do
    printf '%s  raw .../main/%s\n' "$(curl -sS -o /dev/null -w '%{http_code}' \
      https://raw.githubusercontent.com/visgl/react-google-maps/main/$f)" "$f"; done
404  raw .../main/LICENSE
200  raw .../main/LICENSE.md
404  raw .../main/LICENCE
404  raw .../main/license

2. [docs] link reference (line 263)

This is the target of "Please see our [documentation][docs]" on line 66. It carries a trailing slash that the site does not serve.

-[docs]: https://visgl.github.io/react-google-maps/docs/
+[docs]: https://visgl.github.io/react-google-maps/docs

The root cause is the site's own deliberate configuration — website/docusaurus.config.js:18 sets trailingSlash: false, so the build emits no /docs/index.html and the trailing-slash form falls through to the Docusaurus 404 route:

$ grep -n 'trailingSlash' website/docusaurus.config.js
18:  trailingSlash: false,

$ curl -sSL .../docs  | grep -o '<title[^>]*>[^<]*</title>'   # -> Introduction | React Google Maps
$ curl -sSL .../docs/ | grep -o '<title[^>]*>[^<]*</title>'   # -> Page Not Found | React Google Maps

Line 263 was also the only trailing-slash visgl.github.io URL in the whole README (grep -cE '.../[^ ]*/$' README.md → 1); the ten [api-*] definitions above it and [examples] below it already omit it and all resolve.

Verification

Status codes before → after, run against the live site:

404  https://github.com/visgl/react-google-maps/tree/main/LICENSE     (old)
200  https://github.com/visgl/react-google-maps/blob/main/LICENSE.md  (new)
404  https://visgl.github.io/react-google-maps/docs/                  (old)
200  https://visgl.github.io/react-google-maps/docs                   (new)

The two 200s are real pages, not soft-404s — see the <title> check above. Both replacement URLs were re-extracted from the edited README.md and curled again to confirm they are exactly what the file now contains.

Checklist notes

• Tests — not run. test:prettier checks ./src ./examples and test:linter checks src/**, so a root-README.md-only change is outside the suite's scope entirely; test:tsc and test:unit are likewise unaffected. Happy to run the full suite if you'd like it on the record.
• Documentation — no public API added or modified, so no docs/api-reference, upgrade-guide.md or whats-new.md changes are needed.
• Related issue — none open that I could find; this was spotted by link-checking the README.
• Milestone — I can't set labels or milestones on this repo; please apply whichever is appropriate.

Limitation

For defect 2 you could alternatively make the site serve /docs/, but since trailingSlash: false is an intentional setting, the README is the aligned side to change. I deliberately did not rename LICENSE.md, which would be a larger unrequested change.

Thanks a lot! I can still access pages with and without a trailing slash, so not sure what you've been seeing, but removing the slash is consistent with other urls, so...

Also: please don't waste your tokens on something like that :D
