This is a patch for SafeYAML (Jekyll YAML parser) to fix a parsing error.
Updating a text input in CloudCannon to 1,234 saves the value unquoted, allowed by the YAML specification. Jekyll then parses this as a number which can case unexpected results. This patch removes the comma when testing for a number.

# This is a patch for SafeYAML to fix a parsing error.
# It ensures the following is parsed as a string rather than a number:
#
# a_string: 1,234
#
# Rendering this with {{ page.a_string }}
# Unpatched is: 1234
# Patched is: 1,234
