ci: fix e2e templates tests failing on mise shim cwd resolution (#1885)

## 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/`.
