maven udpate fail due to LICENSE.txt rename to LICENSE

[haha4github]

Hi, my maven update failed and throw exception:

Caused by: java.util.concurrent.ExecutionException: java.lang.RuntimeException: Failed to fetch license for com_google_flatbuffers_flatbuffers_java url: https://raw.githubusercontent.com/google/flatbuffers/master/LICENSE.txt

I found https://raw.githubusercontent.com/google/flatbuffers/master/LICENSE.txt is renamed to https://raw.githubusercontent.com/google/flatbuffers/master/LICENSE
but in pom.xml the url is not updated.

Please help update or have both LICENSE.txt and LICENSE there because old versions are all still using .txt to verify the license .

Thanks

@CodeMaster7000 you made this change in #7808. Can you take a look?

[CodeMaster7000]

@dbaileychess That PR has already been merged. I will create a separate PR for this one.

@dbaileychess Since that PR had been merged, I have created #7849 to fix this issue.

This problem persists for flatbuffer version 1.12.0. I know that the version is rather old, but I have no control over transitive dependencies and version 1.12.0 is still in use by com.google.cloud:google-cloud-bigquery:2.25.0.
It there a possibility to patch this change back the old versions?
