Finds the index of all instances of a substring in a string.
The string is indexed over code points using a zero-based index. Only non-overlapping matches are found, starting from the leftmost match.
For example, text.find_all("00000", "00") returns [0, 2]. This indicates
that the substring ("00") has been found in the source string ("00000") at
indexes 0 and 2.
Or, for example, text.find_all("Hello World", "l") returns [2, 3, 9]. This
indicates that the substring ("l") has been found in the source string
("Hello World") at indexes 2, 3, and 9.
