chore: pin techdocs-node to 1.14.4 so that it doesn't use the unavailable toError function

[04kash]

Description

RHDH 1.10 is on Backstage 1.49.4, so the RHDH backend provides @backstage/errors 1.2.7. We were pulling in @backstage/plugin-techdocs-node 1.14.5, which calls toError (added in errors 1.3.0). techdocs-node is bundled into the dynamic plugin, but @backstage/errors is a peerDep — it's not bundled, the RHDH backend provides it at runtime. So techdocs-node's ^1.3.0 declaration only affects the build workspace; it doesn't upgrade what the backend actually loads.

1.14.5 came in through global-header's caret on @backstage/plugin-search-backend-module-techdocs. Yarn resolved that to 0.4.13, which depends on techdocs-node ^1.14.5, and deduped it with the techdocs wrapper's 0.4.12 pin. techdocs-node 1.14.5 did bump its @backstage/errors minimum correctly (#33720); the problem is the RHDH backend still serves 1.2.7.

Fix

Pin @backstage/plugin-techdocs-node to 1.14.4 via resolutions in dynamic-plugins/package.json and the techdocs-backend wrapper, then regenerate dynamic-plugins/yarn.lock.

Alternative was bumping @backstage/errors to ^1.3.0 at the RHDH root.

Without pinning to 1.14.4, the following error is observed when mkdocs.yaml is not writable:

After pinning (with mkdocs.yaml still being non-writable), the correct warning message is shown:
