What changes are included in this PR?

This PR is going to relax the MSRV check thanks to rust 2024. Since starts from rust 2024, cargo has msrv aware dep resolve. This means that dep's upgrade no a problem now.

Are these changes tested?

Would that mean we could undo these two recent commits?
#1783
#1785
If I have time I will try to test this branch with those two commits removed.

Yep, technically we don't need to play the cargo.toml and cargo.lock game anymore.

I checked out this branch (git fetch upstream pull/1795/head:pr-1795-msrv-check && git checkout pr-1795-msrv-check), did a revert on #1783 and #1785 (git revert 104a0167 ddbcae46 --no-edit), and did an MSRV check (make check-msrv) and everything passed. LGTM! Thank you @Xuanwo!
