Fix CI: Pin setuptools_scm<10 to fix api-lint build failure
setuptools-scm 10.0.5 (with its new vcs-versioning dependency) requires
a [tool.setuptools_scm] or [tool.vcs-versioning] section in pyproject.toml.
AWX intentionally omits this section because it uses a custom version
resolution via setup.cfg (version = attr: awx.get_version). The new major
version of setuptools-scm treats the missing section as a fatal error when
building the sdist in tox's isolated build, causing the linters environment
to fail.
Pinning to <10 restores compatibility with the existing version resolution
strategy.
