Add `--reactVersion` argument. This argument is only used in DevTools. When this is specified, run only the tests that have the `// @reactVersion` pragma that satisfies the semver version range. Otherwise, run tests as normal
Update all our local scripts to use `build` instead of `build2`.
There are still downstream scripts that depend on `build2`, though, so
we can't remove it yet.
My personal workflow is to develop against the www-modern release
channel, with the variant flags enabled, because it encompasses the
largest set of features. Then I rely on CI to run the tests against
all the other configurations.
So in practice, I almost always run
```
yarn test -r=www-modern --variant TEST_FILE
```
instead of
```
yarn test TEST_FILE
```
So, I've updated the `yarn test` command to use those options
by default.
