Don’t pin to specific version in README

[bramus]

Right now the README includes the library using its full version. At the time or writing that is 1.0.8

<script src="https://cdn.jsdelivr.net/npm/[email protected]/baseline-status.min.js" type="module"></script>

Because of this, authors that copy-paste the code will never receive bugfixes.

Better is to refer to only the major version, as follows:

<script src="https://cdn.jsdelivr.net/npm/baseline-status@1/baseline-status.min.js" type="module"></script>

When following semver, this should be no problem.

The site developer.chrome.com was affected by this: it was stuck using the wrong Chrome logo because it had pinned [email protected]. I had to manually update that site to load the new version, and immediately opted to load baseline-status@1 from now on so that it always has the latest 1.x version.
