fix: rm find_package outside jana_plugin.cmake (#1710)

### Briefly, what does this PR introduce?

reduce duplication, to ensure the same components are found, and to
ensure we keep track of minimum version requirements.

### What kind of change does this PR introduce?
- [x] Bug fix (issue: code duplication)
- [ ] New feature (issue #__)
- [ ] Documentation update
- [ ] Other: __

### Please check if this PR fulfills the following:
- [ ] Tests for the changes have been added
- [ ] Documentation has been added / updated
- [ ] Changes have been communicated to collaborators

### Does this PR introduce breaking changes? What changes might users
need to make to their code?
No.

### Does this PR change default behavior?
No.
