Sometimes a projects has a lot of secrets (more than 10). And its
cumbersome to write $(kama secrets fetch ...) with a lot of field
names.
I want to be able to just fetch all the fields from a given item
and then just use these with $(kamal extract NAME)
When fetched item is not a login, Bitwarden adapter raises NoMethodError
because the returned JSON does not have the login.password value.
Add a nicer error message for that case.
Avoid outputting this login error message, it wasn't an error and you
don't need to follow those instructions.
```
[ERROR] 2024/09/11 11:57:08 You are not currently signed in. Please run `op signin --help` for instructions
```
Rather than redirecting the global $stdout, which is not never clever in
a threaded program, we'll make the secrets commands aware they are
being inlined, so they return the value instead of printing it.
Additionally we no longer need to interrupt the parent process on error
as we've inlined the command - exit 1 is enough.
