fix(ci): regenerate uv.lock for ogx-client 1.2.0 on release-1.2.x (#6300)

## Summary

`pyproject.toml` on `release-1.2.x` pins `ogx-client==1.2.0`, but the
committed `uv.lock` still resolved `ogx-client` **1.1.3** (and carried a
stale `>=1.1.3` specifier). The pre-commit **uv-lock** check regenerates
the lock and diffs it, so it failed on the branch — this is the
pre-commit failure seen on the `--insecure` backport (#6293).

## Change

Regenerate `uv.lock` to match `pyproject.toml`:

- `ogx-client` 1.1.3 → 1.2.0
- drop the no-longer-required `pyaml` transitive dependency

No source changes; lockfile only.

## Test plan

```
uv lock
pre-commit run uv-lock --files uv.lock   # Passed
```

Separate from the build-job failures on #6293, which are addressed by
the `install-ogx-client` in-repo generation fix (#6297, being backported
to `release-1.2.x`).
