Update license for use with non-VS Code distros (vscodium, headmelted, code-server, etc.)

@sean-mcmanus Pleeeeease update the licence 😃. VS code having a permissive license means people can do their own thing that upstream might not be interested in (e.g. independently packaging it for a distro) but it's a shame that we can't then use some of these standard extensions with it.

From the comments in regards to arm/aarch64 in #429 and #2506 it seems like there should be some sort of solution to address the case of users who want to use a local ARM machine.

The debugger disables itself and may have reason to have a stricter license than the language service component.

Wouldn't be necessary if VS Code would release for Linux ARM: microsoft/vscode#6442 and microsoft/vscode#1031

We are working with our legal team to evaluate our options.

We won't be making changes to our license agreements, but we were able to make progress on ARM/ARM64 versions of VS Code. 😃

Check it out!
