docs: Update GitHub organization references in Trixie guide

Updates references from deprecated zfsonlinux organization to
current openzfs organization.

FAQ link changed to relative reference within openzfs-docs to
avoid redirect loop (wiki redirects to openzfs-docs anyway).

Changes:
- FAQ: Use relative link to docs (avoids wiki redirect loop)
- Commit 82a37189: zfsonlinux → openzfs
- Issue #7734: zfsonlinux → openzfs
- Issue #330: zfsonlinux → openzfs (2 instances)
