Free some dependencies to fix environment solving

Description

Our Python 3.13 + friends environment is not solving anymore https://github.com/ESMValGroup/ESMValTool/actions/runs/20801973056/job/59748587368 but given the OSX (pure Python one) solves well, it must be something to do with friends (R, NCL, etc)

We should be able to get rid of those if we re-enable the pre-commit hook at

ESMValTool/.pre-commit-config.yaml

Lines 45 to 53 in 9bde7d3

	# - repo: https://github.com/lorenzwalthert/precommit/ # Checks for R
	# rev: 'v0.4.2'
	# hooks:
	# - id: style-files # styler
	# - id: lintr
	# - repo: https://github.com/codespell-project/codespell
	# rev: 'v2.3.0'
	# hooks:
	# - id: codespell

and perform the currently failing test using pre-commit instead.

We would just need to pin that pre-commit hook to the version where the checks passed (i.e. the version of the pre-commit hook that uses the versions of lintr and styler listed here).

all fun and games until I realized I lost you at pinning the pre-commit hook - how the heck would we know the version when that hook last passed the test? Unless you want me to write a Monte Carlo routine that loops over lintr hook versions 🤣

[valeriupredoi]

can we not just skip the R-linting test in tests/unit/test_lint.py? I've not seen any of the following in the past 5 years:

• anyone writing a recipe in R
• anyone complaining that our R recipes don't follow R linting standards

[valeriupredoi]

actually, scratch that - it's prob a good idea to have an r-lintr test, let me see what I can do with that pre-commit version, I'll toss some coins 🪙

I've not forgot about this, am gonna try have a look at it tomorrow - sorry, I've been under a lot of snow elsewhere, bud
