Closes #5074

Fixes broken links detected by the linkcheck workflow:

1. Telegram sticker documentation anchors - The anchors #animation-requirements and #video-requirements no longer exist on https://core.telegram.org/stickers. Updated to the new anchors #animated-stickers-and-emoji and #video-stickers-and-emoji.

2. Google Maps documentation URL - The /supported_types endpoint permanently redirects to a legacy page. Updated all occurrences to use /place-types which is the current documentation.

3. GitHub bot user URLs - URLs like https://github.com/dependabot[bot] return 404 due to unencoded square brackets. Added a regex pattern to linkcheck_ignore to skip these bot user profile links.
