Support AWS profiles

[sven-plastiq]

I have a multi-account setup and would like to store my secrets in another account than the current one.
While the plugin supports multiple accounts and ARN the actual AWS command for getting the secret is using the default profile.

I would like to be able to provide another profile that is used to execute the aws secretsmanager get-secret-value command.

This is a majot drawback for this plugin. I would +1 it

Same here, have to change my code because of the lack of profile support.

We would find it very useful as well and have opened a PR for adding basic support to the plugin for now, with more complex support coming soon (if we can get to it lol)
