To sync the tags from one repository to another, you can do the following:

1. Clone the repository that you want the tags to be in, and change to that cloned repository.

git clone git@github.com:prb112/FHIR.git
cd FHIR

2. Add a remote to the original repository.

git remote add fhiro git@github.com:IBM/FHIR.git

3. Check that the remote is there (fhiro).

git remote -v
fhiro	git@github.com:IBM/FHIR.git (fetch)
fhiro	git@github.com:IBM/FHIR.git (push)
origin	git@github.com:prb112/FHIR.git (fetch)
origin	git@github.com:prb112/FHIR.git (push)

4. Fetch the original tags.

git fetch fhiro --prune --tags

5. Check the tags are shown.

git tag --list

6. Remove the remote.

git remote remove fhiro

7. Check that the remote is removed.

git remote -v
origin	git@github.com:prb112/FHIR.git (fetch)
origin	git@github.com:prb112/FHIR.git (push)

8. Push the tags to the new destination.

git push --tags

Note I did disable the GitHub Actions prior, and re-enabled after.
