Allow for typescript pre-release peer dependencies

[TimvdLippe]

In Chrome DevTools, we tend to use beta/release candidates of TypeScript to catch errors early. Currently, we are depending on 4.3.1-rc. However, if we install rollup-plugin-minify-html-template-literals (which has a transitive dependency on this package), we now get a duplicate installation of TypeScript.

This behavior is sadly intentional by npm, as semver doesn't think that 4.3.1-rc matches ^4.0.0. Based on https://survivejs.com/maintenance/packaging/managing-dependencies/#understanding-version-ranges I think it should be possible to update the ^4.0.0 range to ^4.0.0-0 to also include beta releases of any TypeScript 4.x version.

Could we update the dependency version of typescript in this package to include pre-releases of TypeScript 4.x?

I don't see a problem with that. D'you mind sending in a PR?

Urgh that doesn't appear to work 😭 I don't know any workarounds sadly.

I asked the question here: https://twitter.com/TimvdLippe/status/1397509326554738690 Let's hope anybody else knows how to do this.

I ended up filing microsoft/TypeScript#44297 so hopefully we can resolve it in TypeScript land.
