fix docs about allowed filepaths

[jameslamb]

Description

Proposes fixing what appears to be a typo in the documentation. The README refers to paths like pkgs32 as "now allowed", but those paths appear to actually NOT be allowed in conda packages:

conda-verify/conda_verify/checks.py

Lines 354 to 355 in 23a018b

	"""Check the tar archive for unallowed directories."""
	unallowed_directories = {"conda-meta", "conda-bld", "pkgs", "pkgs32", "envs"}

Thanks for your time and consideration.

Checklist - did you ...

• Add a file to the news directory (using the template) for the next release's release notes?
• Add / update necessary tests?
• Add / update outdated documentation?

I've updated this to latest main again.

@jezdez could I please get a review here? Sorry for the @, but I thought it was appropriate given that this repo doesn't auto-assign reviewers, the change is small / non-controversial (I hope), and it's been about 10 months since this was first opened.
