Update to gravity v32 in Main server

[Esteban82]

I will update the grids of faa and vgg to version 32 on the main server. The current version is 31.

The steps to follow are:

• [x] Test the files already in the test server.
• [x] Make a PR with the new gmt_data_server.txt and the earth_faa/vgg_server.txt in this repo.
• [x] Copy and place the updated gravity data from the test server to the main server.
• [x] Merge the PR.
• [x] Update the information in the remote sets repository.
• [x] Close this issue.

I will wait some days to see that there is no problems with the WDMAM 2.1.

The files are already in the test server. The info of the *_server.txt files are also describing version 32.

I think that there were no problems. I see that in the chinese server the files were updated.

So, I will proceed with the issue.

I just copy the files to the main server.
