Document option to Install only from named repo

[kuszewski]

Enhance install to let the user name the repo the package should be installed from.

As the number of repositories grows, the chances of name collision happening occurs. From a security context, this means that a customer could install the wrong package.

Oh, nice!

Could I ask that this find its way to the GitHub Wiki?

[daimor]

Sure, go ahead, and update Wiki. Wiki can't be updated through PR's, so, I can't do it, anymore. Probably, worth migrating to the way as in VSCode-ObjectScript instead of wiki
