{(\d+)} matches {1} or {123} or {89437863896}, but does not
match when there's a non-digit (even a whitespace) inside the
brackets.
If you know that there are no curly braces inside the curly braces
you could use just /{(\d+)(.*?)}/
If you're not sure, /{(\d+)(.*)}/ without the /s switch should also work
as . will not match a newline.
