[CI][Python] Revert pinning miniforge once mamba solver issue is resolved #50004
Description
See #49998 for context.
Once mamba-org/mamba#4274 is fixed and released in miniforge, or we drop Python 3.10 from CI (it's EOL on 2026-10-31), we should revert #49999.

The mamba fix is released in version 2.7.0, but the latest miniforge has pinned the mamba version to 2.5.0. That's before the performance regression, but I think we should wait until they use mamba >=2.7.0 before reverting the version pinning.

This should be doable now - miniforge now uses mamba 2.9.0 and we dropped Python 3.10 from CI anyway.

Thanks for pointing this out @thisisnic, I've opened #51898 to undo the version pinning.
