feat(tools): ts transform to add static version to elements

[bennypowers]

What I did

1. add a typescript transform to a static version property to custom element classes

Testing Instructions

1. run build
2. check that element .js files have a static version property
3. run the dev server
4. customElements.whenDefined('pf-button').then(PfButton => console.log(PfButton.version));
5. copy static-version.cjs into @rhds/elements node_modules, along with the package.json for pfe-tools
6. add { "transform": "@patternfly/pfe-tools/typescript/transformers/static-version.cjs" }, to tsconfig.json
7. remove the static version = '{{version}}' declarations from element files
8. run the build and dev server, and confirm outputs as above.
