/// The regex pattern `<tag>.*?</tag>` explanation:
/// - `<` matches the literal `<` character.
/// - `tag` matches the literal parameter provided to the function, e.g., `style`.
/// - `>` matches the literal `>` character.
/// - `.*?`
/// - `.` matches _any_ character **except** a new line
/// - `*` will match zero or more of the preceeding character, in this case _any_
/// character
/// - `?` switches the matching mode to [lazy](https://javascript.info/regexp-greedy-and-lazy)
/// so it will match as few as characters as possible before satisfying the rest of the pattern.
/// - `<` matches the literal `<` character.
/// - `/` matches the literal `/` character.
/// - `tag` matches the literal parameter provided to the function, e.g., `style`
/// - `>` matches the literal `>` character.

///
/// - Parameter tag: The tag to remove.

/// - Returns: A new copy of `self` with the tag removed.
