Export credential manager API from CLI plugin

[rudyflores]

Resolves #8

Things addressed in this PR:

• Export credential manager API from CLI plugin
• Updated dependencies to latest versions
• Changed author names in packages to Zowe (suggested by @JillieBeanSim :) )
• Optimized bundling times with tsup bundler in combination with turbo! now minimizes extension with terser.
• When activating extension, a constructor for the credential manager can be used for initializing
• Adjusted the .editorconfig to use 4 spaces instead of 2 (was seeing some warnings of this on build command
• Added support for lifecycle methods postInstall and preUninstall

to test: run npm install && npm run build, view the packages/vscode/dist/extension.js file and notice how it's now minimized, this should run without errors.

run npm run package this should bundle, minimize, and pacakge the CLI and .vsix file in the dist directory.
