pyproject.toml value for license key should be a table, not a string

[DavidAntliff]

Please refer:

rpyc/pyproject.toml

Line 11 in 5f41958

license = "MIT"

According to the Packaging Metadata docs, the project.license field should be a table, not a string:

E.g.

license = {text = "MIT License"}

This is currently preventing RPyC being installed with Yocto 4.1:

| ValueError: invalid pyproject.toml config: `project.license`.
| configuration error: `project.license` must be valid exactly by one definition (2 matches found):
| 
|     - keys:
|         'file': {type: string}
|       required: ['file']
|     - keys:
|         'text': {type: string}
|       required: ['text']
| 
| ERROR: 'python3 setup.py bdist_wheel ' execution failed.
