fix(generators): Do not force install of package manager when using ni

[timarnoldev]

Fixes #19945

When having a .lock file from a different package manager ni forces the installation or terminates the task if the user declines.

To overcome this issue when ni is used in cli tools like prisma cl programmatic should be set to true.

Note: the programmatic option was added to ni by @millsp in antfu-collective/ni#151

@millsp is there any reason why this option it was not set to true like done in this PR?

No I don't think there's any reason, it should always be marked as programmatic.
