Bump phf dependency in parcel_selectors crate

[nicoburns]

Context

We're wanting to use lightningcss as a dependency in Taffy. However our CI is complaining that lightningcss is depending on multiple versions of the same crate (which we try to avoid for binary size reasons).

I've tracked this down to parcel_selectors crate which depends on phf 0.8on cssparser 0.29 which depends on phf 0.10.

Changes made

• Updates the parcel_selectors crate to use phf 0.10 (no code changes needed)
• Bumps the version of the parcel_selectors crate to from 0.25.1 to 0.25.2
• Updates the repository field of Cargo.toml to point to this repo
• Updates the documentatation field of Cargo.toml to point to docs for the parcel_selectors crate rather than the selectors crate.

Thanks!

@devongovett Thanks for merging this. Would it be possible to publish the new version of the parcel_selectors crate containing this fix? I think that's all the should be required as it's a semver compatible release.
