Issue

This PR wants to solve the following DEPRECATION WARNING.

DEPRECATION WARNING: TestFixtures.fixture_path is deprecated and will be removed in Rails 7.2. Use .fixture_paths instead.
If multiple fixture paths have been configured with .fixture_paths, then .fixture_path will just return
the first path.

Cause

TestFixtures#fixture_path will be replaced with TestFixtures#fixture_paths in Rails 7.1. TestFixtures#fixture_paths returns the array.

• https://github.com/rails/rails/pull/47764

How to solve

Changed the implementation of the AttachmentExtractTest#fixture_file_path without using TestFixtures#fixture_path

• Previously, it used TestFixtures#fixture_path to create a relative path.
• This relative path was passed forActionDispatch::TestProcess::FixtureFile#fixture_file_upload.
• Now, ActionDispatch::TestProcess::FixtureFile#fixture_file_upload can use absolute paths.
• Therefore, creating a relative path with TestFixtures#fixture_path is no longer necessary.
