Add clarification for case-sensitivity for LicenseRef-

[vargenau]

See #981

[goneall]

This resolves an inconsistency in the spec. Note that the SPDX Java tools does not currently support this clarification, however. There is an existing issue to track updating the SPDX Java tools.

And I would also add this line to the previous paragraph (after "case insensitive.") instead of having it as a separate paragraph.

@zvr
Merging is blocked by DCO.
Should I do something?

[bact]

@vargenau DCO requires you to signed-off the commit again (for every commits).

Is it me or @zvr as he made a change to my commit?

[bact]

Anyone who actually make the commit.
(in this case, zvr only suggested the change but not actually commit the change himself).

Try this to rebase https://github.com/spdx/spdx-spec/pull/984/checks?check_run_id=27520863733
(not always successful, to my experience, as there can be some conflicts that can't be rebased. but still worth a try)

Thank you @bact for your help. It's done.

Please merge.
