TJ Hoplock be5dc65671 chore!: adopt log/slog, drop go-kit/log (#875)
* chore!: adopt log/slog, drop go-kit/log

Requires: prometheus/common#697

This PR includes:
- linter updates to enable `sloglint` linter
- Go dep updates for prometheus/{client_golang,common,exporter-toolkit}
  libs
- refactorings to adopt log/slog in favor of go-kit/log

The bulk of this PR was automated by the following script which is being
used to aid in converting the various exporters/projects to use slog:

https://gist.github.com/tjhop/49f96fb7ebbe55b12deee0b0312d8434

Builds and passes tests locally with go workspaces and up-to-date main
branch of prometheus/common.
