Add --no-cache option to run_pyright script (#24212)

## Summary & Motivation

The `uv` cache can cause subtle problems sometimes when rebuilding
pyright environments. Rebuilding envs without using the cache can fix an
apparently intractable problem. This PR adds `--no-cache` as an arg to
`run-pyright.py`. This is intended for rare use as an escape hatch for
pyright env problems-- it makes rebuilding the envs much more slow.

See this issue I posted over at `uv` for some info about why you might
want to use this: astral-sh/uv#7028

## How I Tested These Changes

My pyright was (unresolvable imports for all dagster packages). After
rebuilding my env with `--no-cache` the problem went away. The issue was
that the cache seemed to be holding `pth` files for our dagster
editables that did not respect `editable_mode=compat` and were
incorrectly formatted for pyright.
