Use short affiliations in AUTHORS.md

[core-man]

Description of proposed changes

Use short affiliations instead of the full ones in AUTHORS.md, because the full affiliations sometimes are longer than one line in GitHub web UI, and more than 200 characters in the plaintext markdown file.

Fixes #897

Reminders

• Run make format and make check to make sure the code follows the style guide.
• Add tests for new features or tests that would have caught the bug that you're fixing.
• Add new public functions/methods/classes to doc/api/index.rst.
• Write detailed docstrings for all functions/methods.
• If adding new functionality, add an example to docstrings or tutorials.

Slash Commands

You can write slash commands (/command) in the first line of a comment to perform
specific operations. Supported slash commands are:

• /format: automatically format and lint the code
• /test-gmt-dev: run full tests on the latest GMT development version

💖 Thanks for opening this pull request! 💖

Please make sure you read our contributing guidelines and abide by our code of conduct.

A few things to keep in mind:

• If you need help writing tests, take a look at the existing ones for inspiration. If you don't know where to start, let us know and we'll walk you through it.
• All new features should be documented. It helps to write the docstrings for your functions/classes before writing the code. This will help you think about your code design and results in better code.
• No matter what, we are really grateful that you put in the effort to do this! 🎉
