Show username in workspace terminal
## Problem
The terminal lacks some quality of life features that many git users have become accustomed to in their local IDEs. For example, we don't show the user name.
<table>
<tr>
<th>GitLab workspace</th>
<th>Local VS Code</th>
</tr>
<tr>
<td>
{width=437 height=117}
</td>
<td>
{width=436 height=100}
</td>
</tr>
</table>
## Solution
Expose the current username in the command line prompt.
