[Bug]: Python SDK: Error parsing since argument in log_commits

[talSofer]

What happened?

The log_commits API endpoint accepts a since query parameter that should be a RFC3339-formatted datetime string. However, when providing a valid ISO-formatted timestamp, the API responds with a 400 Bad Request error.

lakefs.exceptions.BadRequestException: code: 400, reason: Bad Request, body: {'message': 'parameter "since" in query has an error: string doesn\'t match the format "date-time" (regular expression "^[0-9]{4}-(0[0-9]|10|11|12)-([0-2][0-9]|30|31)T[0-9]{2}:[0-9]{2}:[0-9]{2}(.[0-9]+)?(Z|(\\\\+|-)[0-9]{2}:[0-9]{2})?$")\nSchema:\n  {\n    "format": "date-time",\n    "type": "string"\n  }\n\nValue:\n  "2025-06-01T08:20:48.000000+0000"\n'}

Steps to reproduce:

1. Manually create a RFC3339-formatted datetime string
2. call branch.log(since=)
