Added helper script responsible for downloading browser extension binaries to be used at testing (Keychain is on the list atm)

Added filtering out non-json output produced by pnpm --json option, what leads further processing to fail.

npm_publish.sh script should accept local mods (to include generated urls to documentation and version info)

- emsdk to 4.0.1
- TypeScript to 5.7.3
- PlayWright to 1.49
- NodeJS to 20.18.1
- PNPM to 9.15.4

npm_generate_version.sh adjusted to non annotated tags having no taggerdate, so its sorting was invalid. Also prerequisites to generate version for swagger.json files.

npm_generate_version.sh script takes explicit DIST-TAG value to eliminate faulty branch-based detection

Improved npm dist-tag detection in case when given commits belongs also to master & develop branches.

Defined helper script to push generated documentation into local WIKI repo (specific to NPM projects)

pnpm package manager tool upgraded to version 9.1.1 in the emsdk image. Also it is deployed using corepack for better convenience

Defined script to publish npm package ( based on https://gitlab.syncad.com/hive/hive/-/blob/develop/scripts/ci-helpers/npm_publish.sh?ref_type=heads )

Implemented common version of bump_npm_version.sh script ( based on work being originally done in https://gitlab.syncad.com/hive/hive/-/blob/develop/scripts/ci-helpers/bump_npm_version.sh?ref_type=heads )

Docker and script definitions for emscripten toolset (including precompiled boost openssl and sec256k1 libraries)
