feat!: Change updater pr-strategy default to 'update' (#124)

* feat!: Change updater pr-strategy default to 'update'

BREAKING CHANGE: The default value for pr-strategy has been changed from 'create' to 'update'.

Previously, the updater would create separate PRs for each dependency version. Now it maintains a single PR that gets updated with new versions.

To preserve the previous behavior, explicitly set pr-strategy: create in your workflow configuration.

 ### Breaking Changes
 
-Updater and Danger reusable workflows are now composite actions ([#114](https://github.com/getsentry/github-workflows/pull/114))
+- Updater: The default value for `pr-strategy` has been changed from `create` to `update`. ([#124](https://github.com/getsentry/github-workflows/pull/124))
+  This change means the updater will now maintain a single PR that gets updated with new dependency versions (instead of creating separate PRs for each version).
+  If you want to preserve the previous behavior of creating separate PRs, explicitly set `pr-strategy: create` in your workflow:
 
-To update your existing Updater workflows:
-```yaml
-### Before
-  native:
-    uses: getsentry/github-workflows/.github/workflows/updater.yml@v2
+  ```yaml
+  - uses: getsentry/github-workflows/updater@v3
     with:
-      path: scripts/update-sentry-native-ndk.sh
-      name: Native SDK
-    secrets:
-      # If a custom token is used instead, a CI would be triggered on a created PR.
-      api-token: ${{ secrets.CI_DEPLOY_KEY }}
-
-### After
-  native:
-    runs-on: ubuntu-latest
-    steps:
-      - uses: getsentry/github-workflows/updater@v3
-        with:
-          path: scripts/update-sentry-native-ndk.sh
-          name: Native SDK
-          api-token: ${{ secrets.CI_DEPLOY_KEY }}
-```
-
-To update your existing Danger workflows:
-```yaml
-### Before
-  danger:
-    uses: getsentry/github-workflows/.github/workflows/danger.yml@v2
-
-### After
-  danger:
-    runs-on: ubuntu-latest
-    steps:
-      - uses: getsentry/github-workflows/danger@v3
-```
+      # ... other inputs ...
+      pr-strategy: create  # Add this to preserve previous behavior
+  ```
+
+  In case you have existing open PRs created with the `create` strategy, you will need to remove these old branches
+  manually as the new name would be a prefix of the old PRs, which git doesnt' allow.
