Subject: [PATCH] docs(README): sync locale lists with the code
The locale lists for isAlpha, isAlphanumeric, isFloat and isIBAN had
drifted from what the validators actually support, so 32 working locales
weren't discoverable from the docs.
- isAlpha / isAlphanumeric: az-AZ, bn-BD, fa, fa-AF, vi-VN
- isFloat: bn-BD, bn-IN, el-GR, fa-AF, fa-IR, gu-IN, hi-IN, id-ID, kk-KZ,
kn-IN, ku-IQ, ml-IN, or-IN, pa-IN, si-LK, ta-IN, te-IN, vi-VN
- isIBAN: DZ, MA
Each entry was verified against the exported locale lists and checked at
runtime. Docs only, no behaviour change.

If `allow_display_name` is set to true, the validator will also match `Display Name `. If `require_display_name` is set to true, the validator will reject strings without the format `Display Name `. If `allow_utf8_local_part` is set to false, the validator will not allow any non-English UTF8 character in email address' local part. If `require_tld` is set to false, email addresses without a TLD in their domain will also be matched. If `ignore_max_length` is set to true, the validator will not check for the standard max length of an email. If `allow_ip_domain` is set to true, the validator will allow IP addresses in the host part. If `domain_specific_validation` is true, some additional validation will be enabled, e.g. disallowing certain syntactically valid email addresses that are rejected by Gmail. If `blacklisted_chars` receives a string, then the validator will reject emails that include any of the characters in the string, in the name part. If `host_blacklist` is set to an array of strings or regexp, and the part of the email after the `@` symbol matches one of the strings defined in it, the validation fails. If `host_whitelist` is set to an array of strings or regexp, and the part of the email after the `@` symbol matches none of the strings defined in it, the validation fails.
