Docs: workaround for typedoc issue #2802 (backport #7470) [release/4.11.x]

[mergify]

TypeDoc 0.26 introduced a defect which caused modifier tags (@alpha, @beta, etc...) to be absent in certain type reflections - causing various issues with linking. While the bug has been identified and fixed, we need to update our docs build system to ESM (in progress) to consume the new version of TypeDoc. In the meantime, a workaround for the issue is to override the default cascadedModifierTags.
