Update MSRVs to be accurate (#6742)

* Update most MSRVs

* Make cargo-msrv verify every package in repo instead of just a select few and purposefully break arrow-flight msrv

* Add test to ensure workspace rust version is being used at least somewhere

* Fix exit1 => exit 1

* Make arrow-flight work, at the very least, with 'cargo metadata'

* Fix arrow-flight/gen rust-version to make CI pass now

* Get rid of pretty msrv logging as it can't all be displayed

* Do '-mindepth 2' with find to prevent running cargo msrv on the workspace as a whole

* Use correct MSRV for object_store

* remove workspace msrv check

* revert msrv

* push object_store MSRV back down to 1.62.1

* Revert unrelated formatting changes

* Fix object_store msrv
