Description

This PR bumps markdownlint-cli from 0.45.0 to 0.48.0.

It fixes the new issues after having run npm run lint-mdx:

> bootstrap@6.0.0-alpha1 lint-mdx
> markdownlint "site/src/content/**/*.mdx"

⚠️ This won't be backported to v5 as markdownlint-cli is not used in v5. Adding it, IMHO, would cause more issues (resolving the Markdown warnings/issues) than anything. Btw, I've created a new "no-backport-to-v5" label.
