Subject: [PATCH] Bump `protobuf` to `~2.27.1`

`protobuf 2.26` raised its MSRV to 1.52.1, which we are now above.
`protobuf 2.27.0` raised its MSRV to 1.55.0, but this was reverted in
`protobuf 2.27.1`. In any case, it's clear this dependency bumps MSRV in
minor releases, so we should use tilde requirements for it.
