DataSourceViewSet erroneously references a `extras.sync_datasource` permission instead of `core.sync_datasource`

[kkthxbye-code]

NetBox version

v3.5.3

Python version

3.10

Steps to Reproduce

1. Create a local datasource file:///tmp/
2. Create a user testuser with all permissions and the additional permission sync
3. With the new user send a post request to the data-source sync endpoint, e.g. http://127.0.0.1:8001/api/core/data-sources/1/sync/

Expected Behavior

Datasource should be synced as user has all permissions.

Observed Behavior

The API returns:

{
  "detail": "Syncing data sources requires the core.sync_datasource permission."
}

The cause is here, just needs to be changed. Was probably missed when stuff was moved to the core app.

if not request.user.has_perm('extras.sync_datasource'):

Should be core.sync_datasource.
