Maintenance Release

What's Changed

Maintenance updates:

• Patched index.test, and scripts/*-downlevel-dts script, to use fs.rm method, if available (later versions of node v18, etc.), else use fs.rmdir one - The latter is deprecated in later versions of node, and will throw errors when removed (in later versions of node).
• Annotated some @ts-ignores.
• Added notes on dart-sass legacy API, and legacy importer functions.

Depedabot security updates:

• Merged dependabot security update #107 by @elycruz in #108
• Bump qs from 6.5.2 to 6.5.3 by @dependabot in #109
• Bump json5 from 2.2.0 to 2.2.3 by @dependabot in #110

Full Changelog: 1.12.17...1.12.18
