Add tsdoc-unsupported-html-name to allTsdocMessageIds. Fixes #453

[Christopher Pruijsen (cpruijsen)]

Summary

• eslint-plugin-tsdoc crashes on ESLint 9 when reportUnsupportedHtmlElements is enabled, because the parser emits tsdoc-unsupported-html-name and that id was missing from TSDocConfiguration.allTsdocMessageIds (the list the plugin copies into meta.messages).
• Added the missing catalog entry (immediately after tsdoc-malformed-html-name, matching enum order) and a test that every TSDocMessageId is known, including the unsupported-HTML parse path.
• Fixes Eslint-plugin-tsdoc - no messageId / support for "tsdoc-unsupported-html-name" rule #453. Same class of bug as tsdoc-characters-after-block-tag not implemented in eslint plugin #211 / PR Add tsdoc-characters-after-block-tag in allTsdocMessageIds #212.

Decision

• Chose: add 'tsdoc-unsupported-html-name' to the explicit allTsdocMessageIds array, matching Add tsdoc-characters-after-block-tag in allTsdocMessageIds #212, plus a completeness test so the two lists cannot silently drift again.
• Alternative: derive allTsdocMessageIds from the enum (const enums were removed in 0.15.0), and/or also add an eslint-plugin-tsdoc patch changefile so a plugin republish depends on the patched @microsoft/tsdoc.
• Why: smallest reversible fix that matches how this repo already solved the identical ESLint crash. The test is what Add tsdoc-characters-after-block-tag in allTsdocMessageIds #212 did not add, which is why this happened again. Happy to switch to an enum-derived catalog and/or a plugin patch bump if you want that in this PR.

The reporter's stack on #453 names tsdoc-unsupported-html-name as the missing messageId. NodeParser already emits TSDocMessageId.UnsupportedHtmlElementName when reportUnsupportedHtmlElements is true. This is not a missing ESLint rule; there is still one rule, tsdoc/syntax.

Test plan

• allTsdocMessageIds includes every TSDocMessageId enum value fails without the catalog line and passes with it
• unsupported HTML elements report a known message id fails without the catalog line and passes with it
• Full @microsoft/tsdoc tests (257) pass
• rush change --verify accepts the patch changefile under common/changes/@microsoft/tsdoc/
• After publish, confirm eslint-plugin-tsdoc with reportUnsupportedHtmlElements: true reports tsdoc-unsupported-html-name instead of throwing (needs an eslint-plugin-tsdoc release whose @microsoft/tsdoc dependency includes this patch)
