refactor: Remove redundant debug log line from Settings client (#1822)

This PR removes a redundant debug log line from the Settings client.

All the information included in this line is also logged a couple of
lines below, so this line adds no value.

For example currently we see:
```
2025-04-01T09:17:56Z	info	[coord=project:builtin:tags.auto-tagging:tag_397__20250401091216_8007_pagination][gid=384]	Deployment successful
2025-04-01T09:17:56Z	debug	[coord=project:builtin:tags.auto-tagging:tag_489__20250401091216_8007_pagination][gid=81]	Created/Updated object tag_489__20250401091216_8007_pagination (builtin:tags.auto-tagging) with externalId monaco:cHJvamVjdCRidWlsdGluOnRhZ3MuYXV0by10YWdnaW5nJHRhZ180ODlfXzIwMjUwNDAxMDkxMjE2XzgwMDdfcGFnaW5hdGlvbg==

```

Furthermore the extra log line is breaking some E2E tests,
`TestPaginationClassic(...)` and `TestPaginationPlatform(...)`, that
rely on counting the number of these messages to count how a many
objects were created or updated:
