   Bumping the MSRV because the most recent version of a crate has bumped their MSRV does not improve user UX, but prevents users on older versions from compiling. This PR tweaks the CI to avoid this

Review Comment:
   Other options would be to:
   
   * Add a maximum version constraint
   * Check in a lockfile
   
   But both of these have obvious drawbacks, this seemed relatively unintrusive. Hopefully at some point cargo will add MSRV aware resolution so these sort of shenanigans will be handled automatically - https://github.com/rust-lang/cargo/issues/9930
