Support shell-based subshells in Warp

[thegedge]

We're tracking non-shell based REPLs (likeirb, ipython, psql, etc. ) on another GitHub issue > #4082

** List of shell-based subshells Warp supports **

• bash, zsh, fish, gcloud compute ssh, eb ssh, poetry shell, sudo su, etc.

Yeah i think the right UI for this is to continue doing blocks but with some indication that you are in a subshell, similar to how we handle ssh. This should be doable. Please upvote if you want it.

Differentiating User Shells And Subshells

From @shankarshastri via #220

Describe the solution you'd like?

It would be great based on the context, to show to users that currently in shell or subshell mode (For example docker shell container id for docker exec, and in case of ssh to ssh and hostname)

Is your feature request related to a problem? Please describe.

It's always a challenge to know whether we are in actual shell or any subshells.

Poetry (python) creates a subshell. Would be nice if this was supported as well.
