Increase the maximum number of entries in requirements.psd1

[AnatoliB]

The maximum number of entries in requirements.psd1 is 10. The original intent was to protect users from the performance impact of installing too many modules. However, it is creating more problems than it solves:

• It forces some users to specify the entire Az, even when they realize they don't need it, just to bring the number of entries below the limit.
• It does not protect users from potential performance impact anyway: a single module can still be overwhelmingly large.

I propose increasing this limit significantly, perhaps even to MaxInt, but certainly not less than 100.

Consider removing this check from the code base.
