chore: Bump MSRV to 1.46 (#605)

* Actually check MSCV on CI

* check broken_intra_doc_links on CI

* clean up CI

* fix other crates

* bump MSRV to 1.42 because of tracing-core

* attempt to fix http not working on 1.42

* use `--workspace` instead of `--all`

`--all` is deprecated

* make tower-service build on 1.42

* force http version 0.2.4

* actually msrv is 1.46 because of tokio

* fix running `cargo fmt`

* clean up

* also run tests on 1.46

* ignore rustsec in time
