fixed about modal when window size is resized

[sanjay-sol]

Fixes #2565
Ref #2531

Changes:
I have addressed and resolved issue #2565, which involved ensuring that the "Report a bug" and "Code of Conduct" sections no longer exceed the boundaries of the "About" modal when the window size is resized .

The behavior of the about component has been successfully resolved. Prior to the changes, it appeared as follows:

As there haven't been any merged pull requests for issue #2531, I've redesign it to the best of my abilities. I request feedback from @raclim and @lindapaiste regarding whether it's appropriate to retain these changes exclusively for issue #2565. If it's preferable to keep the modifications isolated to this specific issue, I'll be happy to re-submit the pull request with the code affecting issue #2531 removed.

I have verified that this pull request:

• has no linting errors (npm run lint)
• has no test errors (npm run test)
• is from a uniquely-named feature branch and is up to date with the develop branch.
• is descriptively named and links to an issue number, i.e. Fixes #123

Thanks for submitting this!

I think after receiving several issues regarding the About Modal we might want to go with redesigning it for a longer term solution over implementing smaller fixes, so I'm going to close this for now. I'm sorry we weren't able to get this in, but please feel free to join in the megathread discussing the About Modal's design or check out other issues in this repository!
