Fix #3153 - Validate tag before build using OCI regex

[LombardiDaniel]

Fix #3153, but guarantees that it woud raise the appropriate error.

The regex expression is:
^[a-z0-9]+((\.|_|__|-+)[a-z0-9]+)*(\/[a-z0-9]+((\.|_|__|-+)[a-z0-9]+)*)*(:[a-zA-Z0-9_][a-zA-Z0-9._-]{0,127})?$

I made it by combining ^[a-z0-9]+((\.|_|__|-+)[a-z0-9]+)*(\/[a-z0-9]+((\.|_|__|-+)[a-z0-9]+)*)* and the (:[a-zA-Z0-9_][a-zA-Z0-9._-]{0,127})? group. Both expressions are from the opencontainers/distribution-spec repo, as cited in the docker docs.

I also wrote a test for testing a build function call with erroneous tag value.

Thanks for the PR! I just kicked off CI and there's some failures - once those are taken care of, I'll get this merged:

• Lint errors - make ruff (will run inside Docker container)
• Unit tests (need to update example tag) - make unit-test-py3 (will run inside Docker container)

Let me know if you have any trouble

@milas Done! the error was due to me changing the exception type and not updating the test!

👍🏻

Out of curiosity, was it you or the linter that reformatted the test file? (Not a big deal, just surprised)

[LombardiDaniel]

No no, i had made a change to better represent the error, before it was TypeError but changed to errors.DockerException to better represent the scenario. But had forgotten to change the test accordingly
