having git commands document on github pages

[dennisseah]

related to microsoft/bedrock#976
under docs/commands, we have
data.json - contains information of all commands
spk.js - fetch data.json and render the commands accordingly.

in package.json, we added a command, build-cmd-docs. so we can call it once we release a new SPK version, yarn build-cmd-docs. This command creates docs/commands/data.json. Implementation of this command is in tools/generateDoc.ts

@andrebriggs, please enable github pages once this PR is merged. and the url to this page should be
https://catalystcode.github.io/spk/commands/index.html
it should look like this https://dennisseah.github.io/simple/commands/index.html

I only have the md file for spk init. The rest of the team members have to chime in to create the rest of the md files. Or I can get them from guides folder

@dennisseah we should update the release instructions to include instructions about running build-cmd-docs. I believe this should probably be the step before PR in the bump version section. Alternatively we can add the call to the end of the ./scripts/release-version-bump file to reduce manual steps.

@andrebriggs, I have chosen to update release-version-bump file. Hope that it is ok with you. and I have add guides/command-implementation.mdon what developer needs to do when implementing command(s)
