Updates codeshift/cli to use current config spec

[danieldelcore]

Updates codeshift.config to apply the latest config specification.

• Use require instead of require.resolve
• Use .ts instead of .js since the codemods are not bundled (and so we lean on our internal ts parsing)
• Bumps dependencies

@danieldelcore thanks for bumping the codeshift and updating config

Thanks @bobrovnik! Is there anything else I need to do before we merge this one :) ?
