fix(tests): harmonize Jest package version to address test file matching

This harmonizes the versions of Jest installed in Framework to address
an issue reported in Stencil here:
ionic-team/stencil#3785

The issue is essentially that certain test commands, such as this one:

```
npx stencil test --spec --max-workers=2 src/utils/keyboard/test/
```

will, at present, alternate between running the tests as expected and
failing. Not good!

The issue is caused by having different @jest/core, on the one hand, and
jest and jest-cli on the other. After updating jest and jest-cli in a to
match the version of @jest/core (27.5.1) and the issue can no longer be
reproduced.
