[stable-8] Bump league/commonmark from 2.10.1 to 2.10.3

[dependabot]

Bumps league/commonmark from 2.10.1 to 2.10.3.

Release notes

Sourced from league/commonmark's releases.

2.10.3

Fixed

• Fixed footnote links and backlinks pointing at the wrong anchor when footnote/footnote_id_prefix or footnote/ref_id_prefix contains an uppercase character; the configured prefix is now emitted verbatim in the href as it already was in the matching id (#524)
• Fixed inline raw HTML tags being escaped when the tag name or an attribute name contains an uppercase letter, such as <svg viewBox="..."> or <Warning> (#1096)

2.10.2

This is a security release to address a denial of service vulnerability in the Table extension and a raw HTML filtering bypass in the DisallowedRawHtml extension.

Changed

• Improved performance of parsing table delimiter rows and splitting table rows into cells by scanning bytes directly instead of stepping a Cursor (roughly 4x faster for delimiter rows and 6x for cell splitting, and more on multibyte rows)

Fixed

• Fixed DisallowedRawHtmlRenderer not blocking raw HTML that ends with a disallowed tag name, such as a line containing only <script (GHSA-97jj-33gv-5xf9)
• Fixed quadratic-time parsing of long paragraphs when the Table extension is enabled (GHSA-3q6v-r5mr-hxv8)
• Fixed table detection to match the GFM spec and reference implementation:
  • Header rows no longer require a | character
  • Header rows must now have the same number of cells as the delimiter row (previously, fewer cells were accepted)
