Bumps regex from 1.5.4 to 1.5.5.

Changelog

Sourced from regex's changelog.

1.5.5 (2022-03-08)

This releases fixes a security bug in the regex compiler. This bug permits a vector for a denial-of-service attack in cases where the regex being compiled is untrusted. There are no known problems where the regex is itself trusted, including in cases of untrusted haystacks.

• SECURITY #GHSA-m5pq-gvj9-9vr8: Fixes a bug in the regex compiler where empty sub-expressions subverted the existing mitigations in place to enforce a size limit on compiled regexes. The Rust Security Response WG published an advisory about this: https://groups.google.com/g/rustlang-security-announcements/c/NcNNL1Jq7Yw
