ci: keep the pre-release version in the sdist build

[TheGupta2012]

The pre-release workflow published its wheels as 1.1.0a0 and its source
distribution as 1.1.0. PyPI rejected the sdist, because 1.1.0 is the released
version and that filename is taken:

400 File already exists ('pyqasm-1.1.0.tar.gz', with blake2_256 hash 'ee5726da…')

Failing run: https://github.com/qBraid/pyqasm/actions/runs/32816030134/job/97705288550

The Source distribution job has two steps that fight each other. Update pre-release version runs pre_build.sh, which writes the stamped version into
pyproject.toml:

Deploying pre-release version '1.1.0-a.0'
Setting version to 1.1.0-a.0

Build source distribution then runs build_sdist.sh, whose first commands were
git reset --hard HEAD and git clean -xdf. pyproject.toml carries a static
version, so the reset restored 1.1.0 and the sdist was built under it:

creating pyqasm-1.1.0

The wheels escape this because cibuildwheel runs pre_build.sh as
CIBW_BEFORE_BUILD, inside each wheel build, with nothing resetting the tree
afterwards.

pre_build.sh already begins with the same reset, so this removes the second one.
release.yml is unaffected: its sdist job builds straight from a fresh checkout.
The script also no longer destroys uncommitted work when a developer runs it
locally.

Where the reset came from

6719abd (#142, 2025-02-20) added it to pre_build.sh and build_sdist.sh
together, as a blanket "every build script starts from a clean tree" rule. Back
then the version came from setuptools_scm, which derives it from git state and
appends a dirty marker when the tree has uncommitted changes. pre_build.sh
dirties the tree by design, since toml set edits a tracked file. That was the
version discrepancy the PR title names, and the same commit added the other two
halves of the fix: version_scheme = "no-guess-dev" and the RELEASE_BUILD
assertion in test_sdist.sh that importlib.metadata.version equals
pyqasm.__version__.

5de7acd (#145) removed setuptools_scm the next day and added
bin/write_version_file.py, which reads the version out of pyproject.toml.
The version no longer depends on git cleanliness, and pyproject.toml became the
one input the pre-release step must set. The reset outlived its reason and now
only undoes that step.

Verified

Stamping pyproject.toml to 1.1.0a0 and running the patched script locally
produces dist/pyqasm-1.1.0a0.tar.gz. The same setup produced
pyqasm-1.1.0.tar.gz before the change.
