[cargo](deps): Bump regex from 1.9.1 to 1.9.4

[dependabot[bot]]

Bumps regex from 1.9.1 to 1.9.4.

Changelog

Sourced from regex's changelog.

1.9.4 (2023-08-26)

This is a patch release that fixes a bug where RegexSet::is_match(..) could incorrectly return false (even when RegexSet::matches(..).matched_any() returns true).

Bug fixes:

• [BUG #1070](rust-lang/regex#1070): Fix a bug where a prefilter was incorrectly configured for a RegexSet.

1.9.3 (2023-08-05)

This is a patch release that fixes a bug where some searches could result in incorrect match offsets being reported. It is difficult to characterize the types of regexes susceptible to this bug. They generally involve patterns that contain no prefix or suffix literals, but have an inner literal along with a regex prefix that can conditionally match.

Bug fixes:

• [BUG #1060](rust-lang/regex#1060): Fix a bug with the reverse inner literal optimization reporting incorrect match offsets.

1.9.2 (2023-08-05)

This is a patch release that fixes another memory usage regression. This particular regression occurred only when using a RegexSet. In some cases, much more heap memory (by one or two orders of magnitude) was allocated than in versions prior to 1.9.0.

Bug fixes:

• [BUG #1059](rust-lang/regex#1059): Fix a memory usage regression when using a RegexSet.

Looks like regex is up-to-date now, so this is no longer needed.
