Bump the npm_and_yarn group across 1 directory with 3 updates

[dependabot]

Bumps the npm_and_yarn group with 3 updates in the / directory: baseline-browser-mapping, browserslist and js-yaml.

Updates baseline-browser-mapping from 2.10.0 to 2.11.21

Release notes

Sourced from baseline-browser-mapping's releases.

v2.11.0

What's Changed in 2.11.0

• feat: Adds a new getTimeline() method for getting the series of minimum browser changes, either grouped by date or by browser.
• refactor: Substantial refactoring of the data compression process that replaces the full list of browsers from @mdn/browser-compat-data and downstream-browsers.json and features from web-features (in their very pared down form) with a change-list timeline that reflects which versions supported Baseline (newly available) on a given date. Thanks to @​swwind for the idea!
• refactor: Some common functions have been moved to a util.ts module for use in other scripts.
• fix: Removes process.exit() calls when unsupported option combinations are passed to getCompatibleVersions() and getAllVersions() in favour of throwing an Error. There is a small security risk with process.exit() calls that sites accepting unsanitised inputs could be the subject of attacks. Unsupported config options now throw and Error which should allow for more graceful handling. Thanks to @​bnbdr for flagging this as vulnerability CVE-2026-45819 .

Fixes #134
