fix(pet-conda): shorten Windows test fixture path

[benogeorge]

Rename the long conda fixture root so Windows GitHub Actions checkouts stay under the path limit.

This preserves the history-based manager detection coverage while avoiding the long-path failure reported in microsoft#171.

Pull request overview

This PR shortens the conda test fixture directory name to avoid Windows path-length failures in CI while preserving history-based conda manager detection coverage.

Changes:

• Renames the long conda-history fixture root to conda_hist and updates the corresponding Rust test to use the new path.
• Adds/relocates conda installation fixture metadata under the shorter path so is_conda_install() and version parsing continue to work.
• Introduces a history_template fixture used to generate a runtime-correct conda-meta/history for the test.

• The fixture history file hard-codes a GitHub Actions workspace path (/home/runner/work/...). This makes the fixture non-portable and inconsistent with the other conda history fixtures (which use a generic non-existent user path) and with the new history_template approach in the test. Consider replacing the hard-coded prefix with the same <CONDA_INSTALL> placeholder (or a generic stable path) so the checked-in fixture content remains environment-independent.
