dtc tar file inside container is actually HTML

[AlexanderWells-diamond]

The file /tar-files/dtc-1.7.0.tar.gz inside the most recent container version (4.0a7) is not actually an archive, it's HTML:

# file /tar-files/dtc-1.7.0.tar.gz
/tar-files/dtc-1.7.0.tar.gz: HTML document, ASCII text, with very long lines

It appears to contain an "Invalid Request" HTML file. I assume something went wrong during the curl command in the tar-files.sh script.

The solution is probably to regenerate the container, and possibly add some sanity checking that the downloaded files are what we expect?

I have re-generated and released the container and it has now correctly obtained dtc-1.7.0.tar.gz. I will look into adding some checks to ensure its correct in the rootfs CI
