This is in response to #6715: e8bb8dffa1
The pre-commit actions have a higher MSRV than the overall project (1.70.0),
so if 1.70.0 is the configured default, this lead to problems (#6730).
This commit fixes the situation by specifying 'stable', whatever that means on the user's system.
These are not being fixed, so it does not make sense to constantly
take on new lints. The fmts may never be stabilized. Currently,
you can not even commit, because it errors out. At least switch to
lints that make it to stable when they are released.
it was showing:
[WARNING] normalizing pre-commit configuration to a top-level map. support for top level list will be removed in a future version. run: `pre-commit migrate-config` to automatically fix this.
