Open VSX Registry: Awareness and Important Steps

@orblazer has published this extension in the [Open VSX Registry](https://open-vsx.org/extension/apollographql/vscode-apollo).

The service was recently transferred to the Eclipse Foundation and we want to ensure a seamless transition for our users. To ensure uninterrupted service and more exposure for your extension, I recommend the following.

**To the maintainers**: If you would like to take over publishing to open-vsx.org, here’s how: https://github.com/eclipse/openvsx/wiki/Publishing-Extensions

**To the current publisher**: @orblazer Please sign the [Eclipse Publisher Agreement](https://www.eclipse.org/legal/documents/eclipse-openvsx-publisher-agreement.pdf). The signing process is [explained in the Wiki](https://github.com/eclipse/openvsx/wiki/Publishing-Extensions) (steps 1 and 2).

**Claiming ownership of the namespace for your extension(s)**. To find out how to do this, see:
https://github.com/eclipse/openvsx/wiki/Namespace-Access
As owner you can add more namespace members (including service accounts) yourself in https://open-vsx.org/user-settings/namespaces. Note that publishing can be done by any contributor to the extension, namely those you add as namespace members once they have signed the Publisher Agreement as well.

Please also note that a license is now mandatory for publishing your extension to Open VSX. If your project doesn't have any license, please add one, preferably an [open source license](https://opensource.org/licenses) such as MIT. The publishing tool [ovsx](https://www.npmjs.com/package/ovsx) offers to automatically add the MIT license when you try to publish without a license.

Today, there’s growing momentum around open source tools and technologies that support Visual Studio (VS) Code extensions. Leading global organizations are adopting these tools and technologies. This momentum has spurred demand for a marketplace without restrictions and limitations. We hope you join us on this journey as we continue to build the Open VSX community.
We look forward to continued innovation from you in 2021!

Review the Open VSX Publishing Extensions, Namespace Access, Publisher Agreement, and FAQ links in the issue, along with the extension's current publishing arrangement. Done means the maintainers or current publisher have addressed the agreement, namespace ownership, licensing, and publishing-transition steps described there.
