fix(jest): use correct minimum jest version

[rwaskiewicz]

What is the current behavior?

When a user attempts to use jest 24, they are greeted with an error:

$ npm t

> new-test@0.0.1 test
> stencil test --spec --e2e

[51:38.0]  @stencil/core
[51:38.1]  v4.3.0 🐫

[ ERROR ]  Please install supported versions of dev dependencies with either npm or yarn.
           npm install --save-dev jest@27.0.3

GitHub Issue Number: N/A

What is the new behavior?

this commit updates the check for the minimum allowed version of jest from v24.9.1 to v24.9.0. while working on the jest refactoring, it was discovered that v24.9.1 does not exist, making it impossible for anyone to use v24

Does this introduce a breaking change?

• Yes
• No

Testing

You can validate the bug exists today by trying to use Jest 24 in a new component starter project:

cd /tmp \
&& npm init stencil@latest component jest-24-test \
&& cd $_ \
&& npm i jest@24 jest-cli@24 @types/jest@24 \
&& npm t

> new-test@0.0.1 test
> stencil test --spec --e2e

[51:38.0]  @stencil/core
[51:38.1]  v4.3.0 🐫

[ ERROR ]  Please install supported versions of dev dependencies with either npm or yarn.
           npm install --save-dev jest@27.0.3

To verify this fix, build this branch:

npm ci \
&& npm run clean \
&& npm run build \
&& npm pack

Then spun up a new stencil component library with it:

cd /tmp \
&& npm init stencil@latest component jest-fix-test \
&& cd $_ \
&& npm i [PATH_TO_TARBALL] \
&& npm i jest@24 jest-cli@24 @types/jest@24 \
&& npm t

Other information

this commit updates the component starter ci tests to run each version of
jest that we support

That's the same number of errors on main, so at least we're not creating new ones!

Wow 😂

[alicewriteswrongs]

😬 I guess there aren't a lot of Jest 24 users out there!
