chore: bump mermaid version to v10.9.3

Updates the bundled version of dependencies in the following files:

- `dist/mermaid.min.js`
- `dist/mermaid.js`
- `dist/mermaid.esm.mjs`
- `dist/mermaid.esm.min.mjs`

**If you are not using these files
(e.g. you are using the default NPM export of `mermaid`,
 e.g. `import mermaid from 'mermaid'`,
 or you are using `dist/mermaid.core.mjs`),
this release is identical to v10.9.2.**

This is to avoid potential security issues in KaTeX and DOMPurify, see:

- GHSA-mmhx-hmjr-r674
- GHSA-64fm-8hw2-v72w
- GHSA-cvr6-37gx-v8wc
- GHSA-f98w-7cxr-ff2h
- GHSA-3wc5-fcw2-2329

These dependencies have already been updated in
[v11.0.0](https://github.com/mermaid-js/mermaid/releases/tag/v11.0.0).
