Remove Lerna

[dkundel]

Work Included:

• Replace lerna for bootstrapping and task running in favor of npm workspaces
• Upgrade TypeScript to 4.9.4
• Upgrade Jest and ts-jest
• Replace lerna in favor of changesets for versioning
• Setup release pipeline through GitHub Actions similar to github.com/twilio-labs/plugin-webhook

Known Issues:

• The requireFromProject.test.ts files are currently partially disabled because npm workspaces hoists the twilio dependency to the root node_modules folder instead of having multiple instances. This results in the test no longer working. Virual mocks might be an alternative but needs validation.`
• skipLibCheck is currently enabled in the tsconfig.base.json because @types/inquirer and execa were throwing issues --> Moved to Turn off skipLibCheck in tsconfig #451
• useUnknownInCatchVariables is currently disabled as it was a breaking change between TypeScript 3.x and 4.4 and requires code changes. --> Moved to Re-enable useUnknownInCatchVariables #452
• Netlify build is currently failing.

some notes, mostly about version choices. None of these are blocking, LGTM otherwise :)

Looks good to me. But left minor comments.
