Bugs Fixed

• The MySql.Data.OpenTelemetry.dll metadata reported the version as 0.0.0.0. (Bug #37198051)

  Our thanks to Ryan Kelly for the contribution. (Bug #115853, Bug #36960454)

• The MySQLUpdateSqlGenerator class now inherits from UpdateAndSelectSqlGenerator instead of UpdateSqlGenerator.

  Our thanks to Hikari Fujioka for the contribution. (Bug #115020, Bug #36624158)

• Added a NULL check to the MySQLActivitySource class.

  Our thanks to Maximilian Bienhüls for the contribution. (Bug #114457, Bug #36568102)

• Added a new rewritebatchedstatements connection option that makes the connector rewrite batched statements and execute them all at once in a single block rather than one at a time, which is default behavior.

  Note that this connection option impacts functions like LAST_INSERT_ID().
