mise doctor command does not have an option not to check of newer version

[ssbarnea]

I tried to use mise doctor on CI in order to ensure that the newly installed mise was setup correctly by https://github.com/jdx/mise-action/tree/v2/ but I discovered that it was failing reporting an outdated miss,... bit ironic considering that was installed few seconds before.

new mise version 2024.12.22 available, currently on 2024.12.21

I think that we need a switch or env variable that does disable to version check, especially as an outdated version changes the return code of mise doctor.

I did a brief grep on the source code and apparently there is no undocumented way to do it.

I'd accept a PR to move this to a warning, there are already warning and error checks so it should be simple

This has since been implemented in #5317 and released in mise v2025.6.3.

An available mise update is now recorded as a warning rather than a doctor error. mise doctor may still display:

new mise version ... available, currently on ...

but that warning alone no longer causes a non-zero exit code. The command only exits with status 1 when an actual doctor error is found.

This means mise doctor can now be used in CI without failing solely because a newer mise release appeared immediately after installation.
