docs: drop refs to embeddedos-org/embeddedos-org namesake (now archived)

README.md: replace the embeddedos-org row in the Related Meta-Repos table with the new embeddedos-org/.github row (the actual home of the org profile, default CONTRIBUTING.md, SECURITY.md, CODE_OF_CONDUCT.md, issue and PR templates, and the canon validator).

get-involved.html: repoint the Contribution guide button to embeddedos-org/.github/blob/main/CONTRIBUTING.md (the canonical org-wide guide). Replace the obsolete embeddedos-org repo tile with an eFab tile (the only meta-repo that ships actual user-facing artefacts beyond the site itself).

No URLs that exist today were broken. Canon clean (34 files scanned, 0 violations).
