docs: remove link to archived project

[EricCrosson]

I archived the upstream project, https://github.com/EricCrosson/patch-semantic-release-npm-for-msr, since it is a much-inferior way to do the same thing as @semrel-extra/npm.

This commit removes the readme's hyperlink to the archived project.

Additionally, drive-by fix a few typos.
