fix: CI support multiple rust toolchians

[greenhandatsjtu]

For now, CI only use stable toolchain: https://github.com/casbin-rs/actix-casbin-auth/blob/05a4a269d60494fdeaf26562e8a4d5db9a695b7c/.github/workflows/ci.yml#L28 For example, in Auto Build CI (ubuntu-latest, nightly), stable toolchain is installed instead of nightly: https://github.com/casbin-rs/actix-casbin-auth/runs/5624601470?check_suite_focus=true#step:3:41

I fixed this issues by replacing toolchain: stable with toolchain: ${{ matrix.rust }}, now it works fine: https://github.com/greenhandatsjtu/actix-casbin-auth/runs/6284623554?check_suite_focus=true#step:3:49

@smrpn @hackerchai @PsiACE @GopherJ please review

This is great, but it needs some tweaking. Things like fmt check and clippy don't need to be run on all toolchains, I think they just need to be passed on nightly.

Hi @PsiACE , I've add a commit, now fmt check and clippy are executed only on nightly, please review again, thank you!

What do you think if we just run fmt check and clippy under linux(nightly)?

Thanks for your advice! Sorry that I didn't think carefully, I've add a commit for it.
