pip fails installing packages due to incorrect python version

[squigjess]

Describe the bug
When this action attempts to install packages that require a later version of Python, pip fails, stopping the whole action.

To Reproduce
Steps to reproduce the behavior:

1. In the project's requirements.txt file, include a package that does not run on Python versions prior to 3.8 (e.g. nextcord).
2. Attempt to run the workflow.

Expected behavior
The action completes successfully.

Error message

ERROR: Could not find a version that satisfies the requirement nextcord==2.0.0a3 (from versions: none)
ERROR: No matching distribution found for nextcord==2.0.0a3

Additional context
If there was a way to change which version of Python gets used, this would resolve the issue, as some projects only support the more recent versions of Python (e.g. my project expects 3.9 to be present).

They both are sourced from the same dockerfile so the same solution may apply to both 👍
