Description

Remove the following messages from the GRASS pylint disable list in pyproject.toml, and remove a duplicate W0621 entry:

• Commit 1: duplicate W0621 entry removed.
• Commit 2: W0133, W0707, W0614, W4901, R0901 enabled. Full local run had no findings.
• Commit 3: E0633, E1123, E1124, E1133, W0632, W4902 enabled. These depend on inference, so no findings locally without the GRASS runtime installed; CI is the check for this commit.
• Commit 4: W4902 disabled again. CI reports deprecated-method on ten open() calls that the local run does not reproduce, so the rule stays disabled until the difference is understood.

No code changes.

Motivation and context

The pylint configuration was ported with a long list of disabled messages. These rules have no findings in the repository, so enabling them prevents new violations at no cost. Other disabled rules with findings are left for follow-up.

How has this been tested?

• Ran pylint 4.1.2 (the version pinned in the Python Code Quality workflow) over the whole repository with the new pyproject.toml, matching the CI command: exit 0, no messages.
• The CI workflow runs the same command with the GRASS runtime installed, which can change inference-based results. The CI run on the current head passed.
