Bazel Docs: Fix syntax errors in 8.6 docs.

Fixes #28930

Prompt

You're an experienced tech writer. Your task is to fix all remaining syntax errors in .mdx files in the current directory. You can find syntax errors by running "mint validate".

General rules:

• Only fix files mentioned in the output of "mint validate".
• Do not insert blank lines and do not introduce trailing whitespaces.
• Do not delete any of the text.
• Do not merge three or more lines into a single line.
• Do not replace HTML tables with Markdown tables.

How to fix errors:

• Remove any text before the YAML frontmatter.
• Unexpected symbols outside of code blocks (mostly { and <) can be fixed by surrounding the snippet with backticks.
• Make sure that and tags are self-closing.
• Fix the escaped tags - replace {{ "" }} with (same for _).
• Replace

   blocks with Markdown fenced code blocks (three backticks).

• Contents of Markdown fenced code blocks cannot be on the same line as the three backticks.
• Replace HTML comments with JSX comments.
• For errors: If the element and the text are on a single line, make sure that the matching is on the same line. If the text spans multiple lines, make sure that both and have their own lines, i.e. they are not on the same line as the text.
