Improve "Other" licenses data

[hauten]

https://software.llnl.gov/visualize/#repo-licenses https://software.llnl.gov/radiuss/about/ (I have not created an issue on the RADIUSS repo for this)

Reported by Mark M: I am pretty sure what is happening is that the repos for those projects have created a LICENSE file at the root of the repo that DOES NOT conform to the standard format GitHub is expecting. So, it doesn’t properly recognize those licenses and our pages show them as “Other”.

We could ask the affected projects to fix this and update our license and copyright instructions to explain it.

Example of PR to update Ascent's license: https://github.com/Alpine-DAV/ascent/pull/1574 (moves the copyright and LLNL code release info into the copyright file)
