Meltano

I have a target (`target-airtable`) that I can install using `poetry install` but not using `pip install`, so `meltano install` fails.

Apparently pip doesn’t have access to the `singer-sdk` version that is specified, but poetry does. For `singer-sdk = "^0.3.2"`, poetry installs `0.3.18` , which doesn’t show up under `pip index versions singer-sdk`

Investigating, thought I’d share as I go

OK this one didn’t end up being very interesting. Upgraded pip from 23 to 24 and suddenly it had access to the 0.3.x singer-sdk packages

Also had to install my meltano into a different python version (with a different pip) for `meltano install` to work

(I'm thinking Meltano should probably have an explicit dependency on `pip` so people get a more newish version when they install it)

It would be really helpful to control Meltano’s python/pip version, yes!
