Mypy suggests `types-Pygments` but `--install-types` doesn't install it

Bug Report

(A clear and concise description of what the bug is.)
See below.

To Reproduce

Do from pygments.lexers import ....

mypy file.py would gives:

(3.14) ➜ git: mypy .
error: Library stubs not installed for "pygments.lexers"  [import-untyped]
note: Hint: "python3 -m pip install types-Pygments"
note: (or run "mypy --install-types" to install all missing stub packages)
note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports
error: Library stubs not installed for "pygments"  [import-untyped]

Normally for other packages I would fix by mypy --install-types [--non-interactive] ..

But it doesn't install types-Pygments despite mypy knowing that this stub is missing.

# Ideally, a small sample program that demonstrates the problem.
# Or even better, a reproducible playground link https://mypy-play.net/ (use the "Gist" button)

Expected Behavior

Actual Behavior

Your Environment

• Mypy version used: mypy 1.19.1 (compiled: yes)
• Mypy command-line flags: See above
• Mypy configuration options from mypy.ini (and other config files): No
• Python version used: Python 3.14.3

Commencez par reproduire l’échec signalé de mypy . avec from pygments.lexers import ..., puis suivez le chemin --install-types --non-interactive qui gère le paquet manquant types-Pygments. C’est terminé lorsque la commande installe le paquet de stubs suggéré et que les diagnostics signalant l’absence de stubs ne se produisent plus.
