ci: fix e2e templates tests failing on mise shim cwd resolution

[vdusek]

Summary

The scheduled e2e template tests have been failing on every matrix job since #1874 / #1880 adopted apify/setup-apify-cli-action@v1.0.0. The action installs apify-cli via a mise shim that resolves the apify version by walking up from cwd looking for a mise.toml. Our tests run subprocess.run(['apify', ...], cwd=tmp_path / actor_name) from pytest's default tmp_path (/tmp/pytest-of-runner/...), which is outside MISE_TRUSTED_CONFIG_PATHS and contains no mise config. The shim therefore errors with No version is set for shim: apify.

This mirrors how apify/crawlee handles the same situation in test/e2e/tools.mjs (running apify push from a directory under the project root and setting GIT_CEILING_DIRECTORIES).

Changes

• pyproject.toml: pass --basetemp=./.pytest-tmp to the e2e-templates-tests poe task so pytest's tmp_path lives under the project root, where mise's parent traversal finds the mise.toml written by jdx/mise-action to $GITHUB_WORKSPACE.
• .gitignore: ignore .pytest-tmp.
• tests/e2e/project_template/test_static_crawlers_templates.py: set GIT_CEILING_DIRECTORIES=tmp_path on the apify push call so git stops before reaching the project's .git/.
