adk deploy cloud_run does not respect .gitignore or .gcloudignore

[stevewalker-de]

When running the adk deploy (to cloud_run) command, the process is copying every file in the source directory, regardless of the presence of a .gitignore or .gcloudignore file.

To Reproduce

1. Load ADK project in vs code
2. Add .gitignore (or .gcloudignore) to exclude system/temp/other files
3. Run adk deploy cloud_run ...
4. Console message = 'INFO: Not using ignore file.'

Expected behavior
The process respects the .gitignore file

Desktop (please complete the following information):

• OS: macOS
• Python version 12.1
• ADK Version: 1.22.1

This is a major pain.

I have created a PR #4187 that fixes this issue. This fix ensures that .gitignore, .gcloudignore, and .ae_ignore are respected across all deployment targets (Cloud Run, Agent Engine, GKE).

Maintainers, please take a look when you have a moment. @stevewalker-de, feel free to check it out as well if you'd like. Thank you!
