Bump prometheus-client from 2.1.0 to 4.2.2

[dependabot]

Bumps prometheus-client from 2.1.0 to 4.2.2.

Release notes

Sourced from prometheus-client's releases.

v4.2.2

4.2.2 / 2023-10-31

Codename: 🎃🦇 Spooky type conversion 🦇🎃

Bug fixes

• #296 Stringify non-string job names in push client: Previously, an error would be raised if you passed a symbol as the job name, which is inconsistent with how we handle label values in the rest of the client. This change converts the job name to a string before trying to use it.
• #297 Stringify grouping key values in push client: Same thing as #296, but for grouping key values.

v4.2.1

4.2.1 / 2023-08-04

Codename: If a bug falls in the forest

Bug fixes

• #291 Handle / in job name in Prometheus::Client::Push: Previously, if you included a / in your job name when using the Pushgateway client, you'd get a 400 error back as we didn't encode it properly. We now base64 encode it per the Pushgateway spec.

  It's possible that nobody has hit this bug (/ is fairly unlikely to appear in a job name) or that the error message (a 400 from Pushgateway with a complaint about an odd number of path components) didn't make it look like a bug in the Ruby client. Either way, this hopefully brings us fully in line with the spec!

v4.2.0

4.2.0 / 2023-07-25

Codename: Funny number

Small improvements

• #287 Add Gauge#set_to_current_time: Does what you'd expect - sets a gauge to the current unix epoch timestamp (including fractional seconds).

  Other client libraries have this and it's about time we did!

v4.1.0

4.1.0 / 2023-03-20

Codename: They finally made a point release

Small improvements

• #264 Add JRuby 9.3 to build matrix: JRuby 9.3 was released, and added as an officially supported version
• #273 Add Ruby 3.2 to build matrix: Ruby 3.2 was released, and added as an officially supported version
