Change TTFD timeout to 25 seconds

[stefanosiano]

📜 Description

changed TTFD timeout to 25 seconds, to avoid competing with transaction's timeout

💡 Motivation and Context

Sometimes the timeout of the TTFD span compete with the timeout of the transaction, being both at 30 seconds
Fixes #3831

💚 How did you test it?
