Suggested upgrades fail when newest version of package requires newer Python version

[wkeithvan]

Describe the bug
Suggested updates don't check the installed Python version. For instance, I am working on a Python 3.6.8 project and the latest Pandas version 1.2.0 requires Python 3.7.1+. Clicking the "Install 'pandas' version 1.2.0" button generates the following error:

The following command was executed:
pip install pandas==1.2.0
The exit code: 1
The error output of the command:
ERROR: Could not find a version that satisfies the requirement pandas==1.2.0
ERROR: No matching distribution found for pandas==1.2.0
Non-zero exit code (1)

To Reproduce

1. Create project using older version of Python, like 3.6.8
2. Add requirement to requirements.txt that requires a newer version of Python, like Pandas 1.2.0
3. Click the "Install 'pandas' version 1.2.0" link
4. Error message (see above) appears

Expected behavior
The context menu should either only suggest the newest compatible version (e.g. Pandas 1.1.5 on Python 3.6) and/or inform the user that Python 3.7.1+ is necessary for Pandas 1.2.0
