Update build scripts

[alschmiedt]

The basics

• I branched from develop
• My pull request is against develop
• My code follows the style guide

The details

Resolves

• Adds a script for releasing beta (Script to release beta version #4507)
• Adds a script for publishing
• Updates recompile script for releasing

Proposed Changes

1. Adds a script for publishing beta version. This relies on user input about the version since I think we want this to be next.release.version-beta.0. However, it checks that -beta. is present and that the version doesn't already exist.
2. Publish script -- Packages, checks with the user they are on the correct branch, checks the dist folder for certain files, and then will login and publish.
3. recompile script -- Updated to ask the user whether to update, patch, minor, or major version.
4. Delete package from require cache whenever we get the version number. Not deleting it was causing us to get the incorrect version in blockly_compressed.js.

Reason for Changes

1. There are few extra steps for releasing a beta version that we do not want to mess up.
2. Basically same.
3. I almost forgot to update the major version this release, which would have been a medium ish headache.

Test Coverage

Tested on:

Documentation

Additional Information

I need to uncomment the line that will actually publish.
I will do that and merge after I have a chance to test releasing beta version, or patch, or something with new script.
I can also add a dryrun version similar to samples if people think that would be helpful.

Can this TODO be removed or is this something that still needs to be tested?

[alschmiedt]

This still needs to be here. I am waiting for when we need to publish a patch, or beta version so that I can test.

[moniika]

ok. Could you change to "Uncomment this line and test the next time we publish a patch, or beta version." and/or maybe create an issue that can be linked.
Then others with less context know what that's in there for.

[alschmiedt]

Just tested, so uncommenting this line and removed the npm pack above.
