"C-h b" in the "*gptel-prompt*" buffer doesn't describe the "C-c C-c" and "C-c C-k" keybindings

Please update gptel first -- errors are often fixed by the time they're reported.

• I have updated gptel to the latest commit and tested that the issue still exists

Bug Description

In the *gptel-prompt* buffer typing C-h b to see the key bindings shows terse information:

Key                  Binding
C-c C-c		#<byte-code-function 152>
C-c C-k		#<byte-code-function 69B>

I believe if you use defun's rather than lambda's the help will be clear. Glancing through the code, I think it's coming from gptel-transient.el. For example, gptel-system-prompt-update an gptel-system-prompt-cancel would read easier than "byte-code function xyz".

(Thanks for creating gptel. I'm just getting started with it and it looks excellent).

Backend

None

Steps to Reproduce

1. M-x gptel
2. Type a question
3. C-c M-x gptel-send
4. In the options window, type s followed by s to set the system prompt
5. In the *gprel-prompt* buffer type C-h b you'll see:

Key                  Binding
C-c C-c		#<byte-code-function 152>
C-c C-k		#<byte-code-function 69B>
