[Security Solution][Notes] change upper limit for max unassociated no…

…tes advanced setting to be 10k instead of 1k (#212786)

## Summary

This previous [PR](#194947) made
the maximum number of unassociated notes an advanced settings so that
user can change the value within a certain limit. The intent was to
allow that value to be between 1 and 10,000 (see acceptance criteria of
the [original ticket](#193097))
but we missed one 0 and the maximum value allowed got set to 1000.

This PR fixes that.
