This was mostly done by clippy via `clippy::doc_markdown`.
I then reviewed it to fix words that shouldn't have it or where `--fix`
put the backtick in the wrong location.
This is to bring us into conformance with the [Rust crate ownership
policy](https://forge.rust-lang.org/policies/crate-ownership.html).
Items of note
- `cargo-credential-1password` is declared as Experimental as it is
intended for the community but I was unsure if we wanted to commit to
full support for it. In my mind, the ideal thing to do would be to
expatriate this to 1password.
- `home` is declared as Internal despite its wide use within the
ecosystem.
- `cargo-credential` is declared as Intentional as its an API intended
for the wider ecosystem and I didn't see a reason to declare it
experimental.
- `cargo-platform`, `cargo-util-schemas`, and `crates-io` are declared
as Intentional as they are both used internally and intended for
others to use for logic that integrates with cargo/registries.
I wondered about these being Experimental or Internal instead.
We likely don't want to release these packages every 6 months just for
an MSRV bump.
By moving the MSRV out of the package, `cargo bump-check` will ignore
the MSRV bump.
Inspired by #13266
Like PR 12352 but for homepage and repository
Versions for
* `cargo-credential-1password`
* `cargo-util-schemas`
* `home`
are bumped along with the change.
