Describe the bug
The GitHub action workflow, Documentation and Guides, fails to generate the Osal pdf guide. It attempts to cd to an incorrect directory that doesn't exist.

To Reproduce
Steps to reproduce the behavior:

1. Go to the documentation workflow
2. Modify the if statements on lines 216, 221, and 231 to let the steps continue even if not on the main branch
3. Run the Documentation and Guides workflow
4. See the error in the Osal guide job. Here is the error I received on my fork running on the latest integration candidate branch.

Expected behavior
This GitHub action should generate the expected pdf Osal guide.

Additional Context
The bug originates from this line in the workflow.
