🪲 [Fix]: Update git config even if not default context (#264)

## Description

This pull request includes updates to the PowerShell scripts related to
GitHub context and configuration settings. The most important changes
include a fix to the `Set-GitHubContext` function and an update to the
`Set-GitHubGitConfig` function to improve the clarity of the operation
message.

Changes to GitHub context management:

*
[`src/functions/private/Auth/Context/Set-GitHubContext.ps1`](diffhunk://#diff-600a257f8ea7acdd36413aef2daf597ab69dd5bb3c17ec7d6fed83e15f0af1d7R150-L153):
Fixed the placement of a closing brace to ensure proper execution flow
when setting the GitHub context and Git config.

Changes to GitHub configuration settings:

*
[`src/functions/public/Git/Set-GitHubGitConfig.ps1`](diffhunk://#diff-9b7705b192d0886bb8d7c2ee853a341fee0be08850a23e15955110e7105c803bL59-R59):
Updated the `ShouldProcess` message to include the username and
installation name for better clarity.
