Describe the bug
The following line in the DefaultEmbargoSetter sets the embargo start date on the Bundle READ policy, which breaks Request-a-Copy

https://github.com/DSpace/DSpace/blob/main/dspace-api/src/main/java/org/dspace/embargo/DefaultEmbargoSetter.java#L97

To Reproduce
Steps to reproduce the behavior:

1. Enable a dc.date.embargo field in submission and populate in dspace.cfg#embargo.field.lift
2. Enable request-copy in configuration
3. Submit item with dc.date.embargo set in future
4. Bitstreams will not be visible in Item view
5. Request-copy- cannot be activated

Expected behavior
Bitstream should show with lock next to it. Clicking link should open request a copy form

Recommendation
Remove line to not set embargo start date on Bundle policy
