[Snyk] Fix for 4 vulnerabilities

[uniibu]

Snyk has created this PR to fix 4 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• github-extension/package.json
• github-extension/yarn.lock

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

Vulnerabilities that will be fixed with an upgrade:

	Issue	Score
	Regular Expression Denial of Service (ReDoS) SNYK-JS-CROSSSPAWN-8303230	828
	Use After Free SNYK-JS-ELECTRON-8381010	721
