Run command for generating payload with bash

[ItsDrike]

In #220, I've added a new job to the tox-lint workflow which generates an artifact which we then upload and is used from the status-embed workflow. However in that PR, I didn't notice that this generation was failing for windows each time. This is happening since the job was running a command which couldn't be executed on powershell. This PR fixes that by explicitly stating that the shell for this command should be bash, even on windows.

This isn't something critical since this workflow artifact generation job isn't required for the workflow to pass, but it should be fixed to avoid not being able to access some details about the workflow later in the status-embed job.
