Add rule prefer-repeats

[ST-DDT]

Sometimes you want to run a test multiple times. For that reason vitest-dev/vitest#2652 added the repeats option. This option should be preferable over for each number.

This rule is related to prefer-each, but should be used specifically, if the for loop encapsulates the entire method, runs on integers and the counter isn't used anywhere in the method.
