Bump bootstrap from 5.3.1 to 5.3.2

Bumps bootstrap from 5.3.1 to 5.3.2.

Release notes

Sourced from bootstrap's releases.

v5.3.2

Highlights

• Passing a percentage unit to the global abs() is deprecated since Dart Sass v1.65.0. It resulted in a deprecation warning when compiling Bootstrap with Dart Sass. This has been fixed internally by changing the values passed to the divide() function. The divide() function has not been fixed itself so that we can keep supporting node-sass cross-compatibility. In v6, this won't be an issue as we plan to drop support for node-sass.
• Using multiple ids in a collapse target wasn't working anymore and has been fixed.

Color modes

• Increased color contrast of form range track background in light and dark modes.
• Fixed table state rendering for color modes with a focus on the striped table in dark mode to increase color contrast.
• Allow <mark> color customization for color modes.

Docs

• Added alternative CDNs section in Getting started -> Download.
• Added Discord and Bootstrap subreddit links in README and Getting started -> Introduction:
  • Discord maintained by the community
  • Bootstrap subreddit
