fix: Change type of sentry.dsc.project_id to string

[elramen]

Description

Change the type of sentry.dsc.project_id from integer to string as there is no guarantee that a project id will fit in an i64 (u64 isn't supported by EAP). This prevents issues if we were to change the project id generation logic in the future.
