Fix get_curdir absolute parameter bug - conditional resolve() call

[Copilot]

The get_curdir function in capybara/utils/custom_path.py was not respecting the absolute parameter. When called with absolute=False, it still returned an absolute path instead of a relative path.

Problem:
The issue was on line 23 where .resolve() was called unconditionally:

return path.parent.resolve()  # Always returns absolute path

As shown in the issue screenshot, both calls returned the same absolute path:

get_curdir(__file__)                    # PosixPath('/home/jack/workspace/...')
get_curdir(__file__, absolute=False)    # PosixPath('/home/jack/workspace/...') ❌

Solution:
Changed the return statement to conditionally call .resolve() based on the absolute parameter:

return path.parent.resolve() if absolute else path.parent

After the fix:

• get_curdir(path, absolute=True) returns absolute path (unchanged behavior)
• get_curdir(path, absolute=False) now correctly returns relative path

This ensures backward compatibility since all existing usage in the codebase uses the default absolute=True parameter.

Fixes #29.
