SQL Server docker users may run into an issue that the collector fails to parse certificate from server due to x509: negative serial number. That's because we adopted Go 1.23 starting from contrib v0.121.0:

Before Go 1.23, ParseCertificate accepted certificates with negative serial numbers.
This behavior can be restored by including "x509negativeserial=1" in the GODEBUG environment variable.

This change is actually not in the release notes of Go 1.23.
Since the SQL Server receiver uses the underlying scraperhelper dependency (which raises negative serial number issue) in core repo, should we consider adding a note at the project level?
