feat: Users can now specify a default provider to use with each run config, so they don't need to explicitly specify which to use when wanting to run different applications.

 You can manually specify which run configuration to use with the `--profile` flag. Again, if no profile is found with 
 that name, `gman` will error out.

+### Specifying a Default Provider per Run Config
+All run configs also support the `provider` field, which lets you override the default provider for that specific
+profile. This is useful if you have multiple providers configured and want to use a different one for a specific command
+, but that provider may not be the `default_provider`, and you don't want to have to specify `--provider` on the command
+line every time.
+
+For Example:
+```yaml
+default_provider: local
+run_configs:
+  # `gman aws ...` uses the `aws` provider instead of `local` if no
+  # `--provider` is given.
+  - name: aws
+    # Can be overridden by explicitly specifying a `--provider`
+    provider: aws
+    secrets:
+      - DB_USERNAME
+      - DB_PASSWORD
+  # `gman docker ...` uses the default_provider `local` because no 
+  # `provider` is specified.
+  - name: docker
+    secrets:
+      - MY_APP_API_KEY
+      - MY_APP_DB_PASSWORD
+  # `gman managarr ...` uses the `local` provider; This is useful 
+  # if you change the default provider to something else.
+  - name: managarr
+    provider: local
+    secrets:
+      - RADARR_API_KEY
+      - SONARR_API_KEY
+    files:
+      - /home/user/.config/managarr/config.yml
+```
+
+**Important Note:** Any run config with a `provider` field can be overridden by specifying `--provider` on the command 
+line.

 ### Environment Variable Secret Injection
 
 By default, secrets are injected as environment variables. The two required fields are `name` and `secrets`.
