Replace parentheses in pills ids

From MDN:
Technically, the value for an id attribute may contain any character,
except whitespace characters. However, to avoid inadvertent errors, only
ASCII letters, digits, '_', and '-' should be used and the value for an
id attribute should start with a letter.
