feat: Add HTTP and Adaptive crawler templates

[vdusek]

Description

Adds the missing crawler types to the cookiecutter project template (crawlee create) and the scheduled E2E templates tests:

• http — uses HttpCrawler (no HTML parser, raw bytes).
• adaptive-beautifulsoup — uses AdaptivePlaywrightCrawler.with_beautifulsoup_static_parser().
• adaptive-parsel — uses AdaptivePlaywrightCrawler.with_parsel_static_parser().

Each has its own main_*.py and routes_*.py template files in the same shape as the existing static-parser templates. Cookiecutter extras resolution and Docker base-image selection were extended; the FROM if-ladder in the Dockerfile was refactored into a single set base_image block, and the http-client extra logic was collapsed into one branch.

The e2e templates test (tests/e2e/project_template/test_static_crawlers_templates.py) and the scheduled-tests matrix (.github/workflows/on_schedule_tests.yaml) were extended with the three new crawler types and matching pytest markers, so they get the same coverage as existing types.

Issues

• Closes #ISSUE if applicable (none linked).

Notes

• Adaptive templates install both beautifulsoup and parsel extras regardless of the chosen parser, because AdaptivePlaywrightCrawler imports both bs4 and parsel at module load time. The upstream adaptive-crawler extra in pyproject.toml does not declare these — fixing that is tracked separately.
• Unifying the lists in cookiecutter.json, tests/e2e/conftest.py, the test parametrize block, and the CI matrix into a single source of truth is tracked in a separate proposal (not part of this PR).
