🩹 [Patch]: Adjust GitHubRepository format to show aligned sizes (#507)

This pull request updates the file size formatting logic in
`GitHubFormatter` to ensure consistent output with two decimal places
for all units, including bytes, and adjusts the related tests to match
the new output format. The most important changes are grouped below:

- Fixes #506

File size formatting improvements:

* Modified `FormatFileSize` in `GitHubFormatter.ps1` to always display
byte values with two decimal places (e.g., "0.00 B" instead of "0 B").

Test updates for new formatting:

* Updated test cases in `GitHubFormatter.Tests.ps1` to expect
two-decimal formatting for bytes and adjusted regex patterns to match
the new output (e.g., `\d+[.,]\d{2}\s{2}B`).
* Refactored the test to directly validate the output of the formatter
against the new expected patterns, ensuring the tests accurately reflect
the updated formatting logic.
* Removed outdated comments and redundant test setup to streamline and
clarify the test file.
