chore: bump MSRV and edition

[shekhirin]

One of the dependencies requires edition2024:

error: failed to parse manifest at `/home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/base64ct-1.8.0/Cargo.toml`

Caused by:
  feature `edition2024` is required

  The package requires the Cargo feature called `edition2024`, but that feature is not stabilized in this version of Cargo (1.81.0 (2dbb1af80 2024-08-20)).
  Consider trying a newer version of Cargo (this may require the nightly release).

Let's bump both MSRV and edition.
