Issue: Can't use a test decorated with `@pass_context` in `select`
When used from `select`, tests that are decorated with `@pass_context` fail with the error:

> jinja2.exceptions.TemplateRuntimeError: Attempted to invoke a context test without context.

For example:

```python
from jinja2 import Environment, pass_context

def main():
    env = Environment()
    env.tests["foo"] = is_foo
    output = env.from_string("""

    works: {{ "foo" is foo }}

    {%- for x in ["one", "foo" ] | select("foo") %}
    fails: {{ x }}
    {%- endfor %}

    """).render({})
    print(output)


@pass_context
def is_foo(ctx, s):
    return s == "foo"


if __name__ == "__main__":
    main()
```

Environment:

- Python version: 3.10
- Jinja version: 3.0.3

Pull request description: Pass context to test when using select
This bugfix allows `pass_context` to be used by tests in combination with `select`, which was previously failing because `select` did not pass the context object, and thus the context would remain `None`. 

Fixes #1624.

Regarding the request for updating `CHANGES.rst`: should I add a new version number (i.e. 3.1.3) to the document for this bugfix? I'm assuming that `3.1.x` is the correct target branch for this PR, but I wasn't entirely sure.

Checklist:

- [x] Add tests that demonstrate the correct behavior of the change. Tests should fail without the change.
- [x] Add or update relevant docs, in the docs folder and in code.
- [ ] Add an entry in `CHANGES.rst` summarizing the change and linking to the issue.
- [ ] Add `.. versionchanged::` entries in any relevant code docs.
- [x] Run `pre-commit` hooks and fix any issues.
- [x] Run `pytest` and `tox`, no tests failed.
