[CLI]Update Integrate patch release

[jhnstn]

This adds the ability to integrate patch release into the main apps.

It adds a host version flag (-V) to the release integrate command.

It will also fail if the trying to integrate a patch where the host version is not supplied.

NOTE: This will work for beta fixes but might not work for hot fixes where the release branch no longer exists. Issue to handle hotfixes #239

Testing

Follow the Testing guide to set up the tool to use forked repos.

Note: A patch PR is required on the forked Gutenberg Mobile repo before attempting the patch integration. This can be manually created to avoid requiring a Gutenberg patch PR

• Create a release branch on the forked host apps e.g. release/1.0
• Create a patch release PR on the Gutenberg Mobile fork
• Run the integration command with the GBM patch version
• Notice the failure message requiring a host version for an patch integration
• Run the integration command again but now include the host version e.g. -V 1.0
• The script should open a PR against the release branch

LGTM. The testing instructions passed. Please take note of the one suggestion I left regarding documentation.

Took me awhile to review this after failing miserably to succeed performing the testing instructions. Turns out, 1.07.0 is not a valid semver value! 😄

A leading zero is invalid. This caused the semver parsing to strip the preceding zero, which resulted in the CLI not locating the PR containing the preceding zero.

Suggested change

	go run main.go release status 1.07.0
	go run main.go release status 1.7.0

Oh geez, sorry about that. TIL 1.0X.X is invalid
