Simple convenience function to return an slog.Logger that writes to io.Discard. Originally suggested by @ArthurSens [here](prometheus#686 (comment)), and requested again by @bboreham [here](prometheus/prometheus#14906 (comment)). As Bryan points out in the comment, there's 147 instances where a discard logger is needed, so a consistent utility function to manage them seems helpful.

For: prometheus#14355 Requires a new release of prometheus/common to be cut, as this depends on the following PRs: prometheus/common#694 prometheus/common#697 This commit updates Prometheus to adopt stdlib's log/slog package in favor of go-kit/log. As part of converting to use slog, several other related changes are required to get prometheus working, including: - removed unused logging util func `RateLimit()` - forward ported the util/logging/Deduper logging by implementing a small custom slog.Handler that does the deduping before chaining log calls to the underlying real slog.Logger - move some of the json file logging functionality to use prom/common package functionality - refactored some of the new json file logging for scraping - changes to promql.QueryLogger interface to swap out logging methods for relevant slog sugar wrappers - updated lots of tests that used/replicated custom logging functionality, attempting to keep the logical goal of the tests consistent after the transition - added a healthy amount of `if logger == nil { $makeLogger }` type conditional checks amongst various functions where none were provided -- old code that used the go-kit/log.Logger interface had several places where there were nil references when trying to use functions like `With()` to add keyvals on the new *slog.Logger type Signed-off-by: TJ Hoplock <[email protected]>

Requires: prometheus/common#697 This PR includes: - Go version updates, so that `log/slog` can be used - linter updates to remove configs for `go-kit/log` that are no longer needed, and enable `sloglint` linter - Go dep updates for prometheus/{client_golang,common,exporter-toolkit} libs 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.
