[Dependency Update] update `reqwest` from version `0.11.18` to `0.12.2`

[pixincreate]

reqwest recently released a breaking change (v0.12.0) and is quite a big change that could possibly fix the intermittent connection reset issue.

This is quite a big change and their changelog can be found here: https://github.com/seanmonstar/reqwest/blob/master/CHANGELOG.md

reqwest also hid the internal (not to be used) libraries that also includes serde_json which is used by analytics crate.

This could also lead to compilation issues as reqwest bumped the http version from 0.x to 1.x while actix_web still (v4.5.1) maintains 0.2.9.
