fix(pydocstyle): use uv run --frozen --no-sync to stop touching uv state

`uv run ruff check --select D` triggers `uv sync` on every invocation,
which rebuilds workspace members and writes to uv.lock / .venv install
state. prek then reports these as "files were modified by this hook"
and fails the hook even when no docstring lint errors fire — every
consumer with workspace members on uv saw pydocstyle flapping on each
prek run.

Mirrors the v1.1.4 mypy fix: `uv run --frozen --no-sync` skips
re-sync entirely and uses the existing lockfile / .venv as-is.

Surfaced on html-to-markdown's prek run after the v1.1.9 bump (which
re-enabled godoc-lint and exposed the pydocstyle flap).

 ### Fixed
 
+- `pydocstyle`: stop triggering "files modified by this hook" via `uv run`.
+  The hook ran `uv run ruff check --select D`, which `uv sync`s the workspace
+  on every invocation and touches `uv.lock` / `.venv/`. prek then reports
+  these as "files were modified" and fails the hook even when no docstring
+  lint errors fire. Switched to `uv run --frozen --no-sync` — same mitigation
+  the v1.1.4 mypy hook adopted. Surfaced on html-to-markdown's prek run.

 - `godoc-lint`: fix `golangci-lint` version-detection regex. The v1.1.5
   v2-compat patch used `sed -n 's/.*version v\([0-9]\+\).*/\1/p'`, which
   (a) requires the `v` prefix that current `golangci-lint version` output
