It's very easy to use new rust features without realizing it since the CI and local development workflows may use the latest rust version. We try to keep some backwards compatibility with rust versions to make packaging easier for some OS-level package-managers like Void Linux's. See helix-editor#1881. This change adds a new CI check which uses the cargo-msrv crate to verify an MSRV version recorded in helix-term's Cargo.toml. When changing MSRV, we can then edit `helix-term/Cargo.toml`'s `package.metadata.msrv` key. The MSRV is set at 1.60.0 for the sake of checkmarks on builds but ideally we want to support 1.57.0. The PR that closes helix-editor#2460 should set this MSRV metadata key back to 1.57.0. Closes helix-editor#2482.

We try to keep some backwards compatibility with rust versions to make packaging easier for some OS-level package-managers like Void Linux's. See helix-editor#1881. This change runs the "Check" step for the pinned version of rust in the rust-toolchain.toml file as well as the MSRV version in a matrix. In order to bump the MSRV, we need to edit .github/workflows/msrv-rust-toolchain.toml This commit sets the MSRV as 1.60.0 but a later child commit will reduce the MSRV back to 1.57.0. Closes helix-editor#2482.

It's easy to accidentally bump the MSRV by using a newer Rust feature. We might be able to check that we're adhering to MSRV with
cargo msrv verifyin a job in the CI build.For background: we keep an MSRV that is behind a few versions in order to make packaging easier for some package managers - some package managers have long processes for updating rust versions and using latest stable Rust features may make it impossible to build Helix for those package managers.
