Update pypi owner for this package

[ianhi]

(cc @tacaswell )
Current on pypi (https://pypi.org/project/ipympl/) this project lists the following maintainers:

@ianhi
@blink1073
@SylvainCorlay
@martinRenou

I'm not sure which one of us is the owner, but it is not me.

For long term health of the project I think that the owner on pypi should be the matplotlib organization as is the case for the main matplotlib project:

Somewhat similar on npm. Though also includes @ianthomas23 and seemingly there I have the power to add more maintainers:

@ianhi Martin added me on npmjs so I could manually upload packages part-way through an emergency release. Feel free to remove me from there if you wish.

Thanks for opening that issue @ianhi. It looks like I'm also not an owner on PyPi since I don't have access to settings. I suspect @SylvainCorlay has owner rights.

Concerning releases, we feel like we should make use of jupyter-releaser from now on and use the PyPi trusted publishers mechanism to let Github actions do the release.

I confirmed @SylvainCorlay is an owner and I agree re: trusted publishers.

[tacaswell]

I agree about trusted publisher / using jupyter-releaser.

I am admin on the matplotlib org and can move this project into it if given the access I need on the ipympl side. Before I do that I want to verify that within a pypi organization you can give teams permissions to upload only a subset of projects in the organization (I assume that this is the case) and pull everyone who currently has access over.

[ianhi]

can we do a similar thing with npm? It's unclear to me if any one person is the owner there.

@ianhi Martin added me on npmjs so I could manually upload packages part-way through an emergency release. Feel free to remove me from there if you wish.

You should have pypi access if needing to making releases!

Moved!

The moving process did not revoke any existing access so I'm going to defer going down the path of sorting out teams/ACL on pypi right now.
