Fix: citation links matching edge cases

[OEvgeny]

Fixes #

Changelog Entry

• Fixed citation links are not properly matched against markdown links, in PR #5614, by @OEvgeny

Description

Links are sanitized by micromark before we're matching them to citations. This PR adds a logic to apply the same sanitization for the citation links.

Design

We're reusing micromark-util-sanitize-uri which the engine is using to process links.

Specific Changes

• renderMarkdown.ts to update link handling logic
• added tests: citation/url.html and citation/url.fluent.html
• updated package.json for bundle

-

• I have added tests and executed them locally
• I have updated CHANGELOG.md
• I have updated documentation
