🩹 [Patch]: Add pipeline input to Disconnect-GitHub (#213)

## Description

This pull request includes changes to improve the structure and
organization of tests. The most important changes include adding support
for pipeline input of contexts to `Disconnect-GitHubAccount`,
restructuring test descriptions for better organization, and removing
redundant test files.

Changes to parameter attributes:

*
[`src/functions/public/Auth/Disconnect-GitHubAccount.ps1`](diffhunk://#diff-3774b57dfa8d10fd0436e4abdecba2520b9dc8ae12c39e8b10f3ccb782b40898L45-R45):
Changed the `[Parameter()]` attribute to
`[Parameter(ValueFromPipeline)]` for the `$Context` parameter.

Restructuring of test descriptions:

*
[`tests/GitHub.Tests.ps1`](diffhunk://#diff-0b1d9ba345a583adce874126c13d6edd3f789416bb9c4db5df1e18af3608554cL170-R170):
Replaced `Describe` blocks with `Context` blocks for better organization
and added new contexts for `Rate-Limit`, `Repository`, `Status`, and
`Disconnect` tests.
