use compat mode when uv installing editable packages in make dev_inst…

…all (#24029)

## Summary & Motivation

After wiping my pyright & base virtual envs, I was unable to get pyright
working, hitting [strange errors that dagster imports were not
found](https://dagsterlabs.slack.com/archives/C03A0D72A6T/p1724874346772169):

```python
/Users/ben/repos/dagster/python_modules/libraries/dagster-shell/dagster_shell/__init__.py:
  1:5: Import "dagster._core.libraries" could not be resolved (reportMissingImports)
```

Some Googling turned up that there are [multiple ways to install
editable packages](astral-sh/uv#3898) & the
default behavior of `uv pip install` is to not install packages in
compat mode, which pyright requires.

We [explicitly opt in in our pyright venv building
code](https://github.com/dagster-io/dagster/blob/master/scripts/run-pyright.py#L304),
but I'm wondering if my base editable installs not using compat mode has
some bleed-over to my pyright venv (e.g. the editable install is
shared)? Either way, making this change, rerunning `make dev_install`
and then rerunning `make rebuild_pyright` seemed to fix my issues.
