immutable-data ignoreImmediateMutation option does not work when creating an array with .split()

[QuaidBartolomei]

Bug Report

the functional/immutable-data rule with ignoreImmediateMutation: true will trigger an error when immediately mutating an array created with the string .split() method

Expected behavior

these rules

      'functional/immutable-data': [
        'error',
        {
          ignoreImmediateMutation: true,
        },
      ]

should allow this code:

const x = ''.split('').pop()

Actual behavior

error:

Modifying an array is not allowed

I know the rules are setup correctly because this does not error:

const x = [].pop()

Steps to reproduce

latest version (6.0.0) with the rule snippet above
