chore(web-sdk): Add simple nodejs script to generate top level exports for web-sdk

[Mercurial]

A continuation to this closed PR: #27

According to this protobuf-es repo issue: bufbuild/protobuf-es#455

top-level exports is not yet implemented. The author discribes a similar syntax issue to the original PR above.

Running buf generate proto indeed generates no index.ts (atleast on my side).

Until it is supported, a quick solution is to have a simple (hacky?) NodeJS script that generates for us a index.ts with the exports and include it in the build script for each package.json

Assuming the flow to publishing the web-sdk packages is the folllowing:

buf generate proto
cd <target lib>
npm run build -> tsc compiles pb and connect services definition + index.ts (generated by node script)

Now its ready to be published

npm run publish

I'm not sure how the original index.ts files were generated in the first place so I could be way off in this PR and its all good if thats the case.

P.S the I messed up the PR it thinks that doc.md is changed but its exactly the same as main branch.
