[extension/sumologicextension] removing collector name from credential path for sumologic (#42453)

<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
#### Description

This pr removes the collector name from the local credentials path that
extension uses for authentication. This allows changing the name of the
collector without registration. See #42511

**Changes**
1. Credential key (hashKeyV2) now derives only from InstallationToken
and APIBaseURL.
2. collectorName no longer affects credential storage.
3. Added backward compatibility: falls back to old key (v1) if v2 not
found.
4. On shutdown, v1 credentials are migrated to v2.
5. Updated tests to cover v1 → v2 migration and ensure correct
credential usage.
