Subject: [PATCH] Ruby ERB.new compatibility fix
 https://bugs.webkit.org/show_bug.cgi?id=237035

Reviewed by Fujii Hironori.

ERB.new has changed its calling convention in newer ruby versions.
This was exposed by https://commits.webkit.org/247450@main, which
tried to silence the warning emitted by newer ruby versions.
Unfortunately, this resulted in failures with older ruby versions
(e.g.
https://build.webkit.org/#/builders/46/builds/11387/steps/8/logs/stdio).

Use the compatibility hack suggested by RuboCop to get this working
across ruby versions (without any warnings).
