🚀 [Feature]: Update required version of Context module to 7.0.2 (#306)

## Description

This pull request updates the dependency on `Context` to `7.0.2` which
no longer relies on `SecretStore` and `SecretManagement` PowerShell
modules, but contains its own local vault logic.

### Module Version Updates:

* Updated the required version of the `Context` module from `6.0.0` to
`7.0.2` across multiple files, including `examples/Connecting.ps1`,
`src/functions/private/Auth/Context/Remove-GitHubContext.ps1`,
`src/functions/private/Auth/Context/Set-GitHubContext.ps1`,
`src/functions/private/Auth/DeviceFlow/Update-GitHubUserAccessToken.ps1`,
`src/functions/private/Config/Initialize-GitHubConfig.ps1`,
`src/functions/public/Auth/Context/Get-GitHubContext.ps1`,
`src/functions/public/Config/Remove-GitHubConfig.ps1`, and
`src/functions/public/Config/Set-GitHubConfig.ps1`.

### Code Cleanup:

* Removed references to `Microsoft.PowerShell.SecretManagement` from
`examples/Connecting.ps1`, `tests/GitHub.Tests.ps1`, and
`tools/utilities/Local-Testing.ps1`.
* Cleaned up unused or redundant code in `tests/GitHub.Tests.ps1` by
removing `Get-SecretInfo` and `Get-SecretVault` commands.
