fix: make saml2_enable_sp_initiated bool throughout

[reallocf]

I encountered the following crash with the latest provider version:

panic: interface conversion: interface {} is bool, not string

This line with the new saml integration appears to be the culprit.

Test Plan

• make test locally
• acceptance tests - I ran locally w/o creating a new Snowflake account (it failed in the expected ways). Let me know if you'd like me to go through that process in order to run the acceptance tests / CI tests. Happy to do that, just unsure of protocol with changes this small 👍 thanks!
