Typo in Update-GitHubRepository variable

[amis92]

A typo results in an incorrect URL being built. Because the variable is misspelled, the repository name is not appended to the URL.

PowerShellForGitHub/GitHubRepositories.ps1

Line 616 in 9bdb37c

'UriFragment' = "repos/$OwnerName/$ReposistoryName"

Fix:

- 'UriFragment' = "repos/$OwnerName/$ReposistoryName"
+ 'UriFragment' = "repos/$OwnerName/$RepositoryName"

Once again, great catch @amis92.

This was the only occurrence of this specific typo throughout the project.

I believe these errors you've found to be fairly abnormal errors relative to the rest of the project, and definitely should have been caught by proper tests. I'll get a separate issue opened to increase the testing for this file.
