refactor: update gulps tasks in order to create ESM files

Updated gulp tasks in order to keep up to date with GOV.UK
Create package/govie-esm files and updated package/package.json to point the export to these files
Renamed the package to fit the name inside the package/package.json file
Fixed couple of bugs found during the update
Deleted the README.md files inside each component (they were all making reference to GOV.UK and they weren't bringing any value)
Updated couple of README.md files in order to remove GOV.UK references
Updated Storybook config files to use/reference the new package name

To build up all references

npm i
npm run build:package
npm run build:dist
npm run build:storybook:dist

To run Storybook

npm run storybiook:ci
