gh-gl2gh link in case of insufficient permissions needs to be changed

[FokkoVeegens]

Description

When using gh gl2gh (version 1.33) and having a permissions issue while migrating, the error message points to a generic docs link for GitHub > GitHub migrations. There is a separate link available for GitLab > GitHub migrations which has specific scopes for the GitHub personal access token, that deviate from the one for GitHub > GitHub. The line of code where the link is:

gh-gei/src/Octoshift/InsufficientPermissionsMessageGenerator.cs

Line 6 in b9b3fa1

return $". Please check that:\n (a) you are a member of the `{organizationLogin}` organization,\n (b) you are an organization owner or you have been granted the migrator role and\n (c) your personal access token has the correct scopes.\nFor more information, see https://docs.github.com/en/migrations/using-github-enterprise-importer/preparing-to-migrate-with-github-enterprise-importer/managing-access-for-github-enterprise-importer.";

.

What the error message looks like now:

The correct URL for GitLab is https://docs.github.com/en/enterprise-cloud@latest/migrations/using-github-enterprise-importer/migrate-from-gitlab/manage-access

Reproduction Steps

Create a personal access token that only has "repos" scope and try to run a GitLab to GitHub migration using gh gl2gh.

@FokkoVeegens thanks for creating this issue, the target token should have same permissions regardless of source/extension but it makes sense to link gl2gh to respective gitlab section docs.
