Q IntelliJ plugin does not work if ~/.aws/config is not writable

[SimSaladin]

When using home-manager options to setup ~/.aws/config, the file is made immutable. This breaks (at least) the SSO login in IntelliJ, although the necessary config options are all already in place in the file.

To reproduce

1. Ensure ~/.aws/config is properly configured for Q
2. chmod a-w ~/.aws/config
3. Open Q in IntelliJ and attempt to login (with SSO)
4. See that the plugin throws an error about not being able to write AWS config
5. Close the error; plugin returns back to the beginning login screen

Expected behavior

Login succeeds and opens the Q chat.
