## Summary

Closes #18349

After this change:
- All deprecated rules are deselected by default
- They are only selected if the user specifically selects them by code,
e.g. `--select UP038`
- Thus, `--select ALL --select UP --select UP0` won't select the
deprecated rule UP038
- Documented the change in version policy. From now on, deprecating a
rule should increase the minor version

## Test Plan

Integration tests in "integration_tests.rs"

Also tested with a temporary test package:
```
~> ../../ruff/target/debug/ruff.exe check --select UP038
warning: Rule `UP038` is deprecated and will be removed in a future release.
warning: Detected debug build without --no-cache.
UP038 Use `X | Y` in `isinstance` call instead of `(X, Y)`
 --> main.py:2:11
  |
1 | def main():
2 |     print(isinstance(25, (str, int)))
  |           ^^^^^^^^^^^^^^^^^^^^^^^^^^
  |
help: Convert to `X | Y`

Found 1 error.
No fixes available (1 hidden fix can be enabled with the `--unsafe-fixes` option).
