chore: create script to add named exports of a components to index.js

[OlkaB]

Contributes to #1578

 What did you do?

Added prebuild script to auto add named exports of components

 Why did you do it?

This was option available in Vue2 and change from it large repo requires additional piece of work, so prefer to restore it at source

How have you tested it?

run build script then generated local tgz package and tested in Vue3 repo

Were docs updated if needed?

@davidnixon thank you for a review.

1. I'm not sure where should I place the code you've provided

   const indexDir = path.dirname(INDEX_FILE_PATH);
   return './' + path.relative(indexDir, systemPath);

   the only place, which provides systemPath variable is convertToImportPathRelativeToIndex method. Is this a place which you meant (so match should use the code returned by what you wrote)? Sorry for asking, but I do not know how GH pipelines works or how to check it, as locally it works for me (which seems not to be helpful in this case😌).

   2. addressed - underscored components are now not included
   3. I've moved script to ci-check as you've suggested

   btw. this is what I receive in ./src/index.js when running locally

Sorry yeah I just replaced the contents of convertToImportPathRelativeToIndex with

function convertToImportPathRelativeToIndex(systemPath) {
   const indexDir = path.dirname(INDEX_FILE_PATH);
   return './' + path.relative(indexDir, systemPath);
}

That works for me locally. I think I see the issue. You are on a windows box I think? So this regex const UNNECESSARY_SYSTEM_PATH_CHUNK_REGEX = /.*\\src\\(.*)/; works if I flip to \ to \/. If the path.relative I think that's a clear look to the function.

Indeed - I'm working on Windows machine. Thank you very much for the help and explanation. I've made a changes as suggested.
