fix: Increase timeout when checking installed Nightly extension.

[Pawel-Szydlo]

Description

When the user has a dozen extensions, Nightly has stopped detecting correctly. Nightly is injected a few milliseconds later.

Increasing the time to check whether an extension is installed solves this problem.

Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. List any dependencies that are required for this change.
