Ubuntu 22.04, Python 3.10, and broken virtual environment layouts

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Ubuntu Jammy

• Poetry version: 1.2.0

• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/colindean/27d36dcc7cf78f722f374ebd5bfd970f (also contains log output and a brief description of env setup steps)

Issue

root@80d0e404badc:/what# poetry self add poetry-plugin-bundle
Using version ^1.0.0 for poetry-plugin-bundle

Updating dependencies

[Errno 2] No such file or directory: 'python'

I believe the problem is in here:

https://github.com/python-poetry/poetry/blob/f1af3f8eec26112b7271c4d3c602957d08cff3a9/src/poetry/utils/env.py#L1231-L1248

Ubuntu doesn't provide a python command anymore, just python3:

root@80d0e404badc:/what# python --version
bash: python: command not found
root@80d0e404badc:/what# python3 --version
Python 3.10.4

Seeing as though all supported versions of Python on which Poetry runs should also provide a python3 executable, perhaps the fallback here should be python3?

https://github.com/python-poetry/poetry/blob/f1af3f8eec26112b7271c4d3c602957d08cff3a9/src/poetry/utils/env.py#L1178

Start with src/poetry/utils/env.py around lines 1178 and 1231-1248, then reproduce poetry self add poetry-plugin-bundle on Ubuntu 22.04 with Python 3.10. Compare the environment executable fallback with the available python3 command; done means the reported dependency update no longer fails because python is absent.
