[feature request] integrate fzf for adding context

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

Linux 5.10.234-206.910.amzn2int.x86_64 - Amazon Linux 2

### Expected behaviour

Here is the idea of the feature request:

so you can use fzf (open source) to add context directly from the q chat session. (And really you could probably setup fzf for removing existing context as well)
