"invalid group specifier name" on MacOS Safari

[romkavt]

Hello!

asciidoctor-kroki.js version 0.12
On Safari 14.0.3 with MacOS 10.15.7 (Catalina) the PlantUML diagrams doesn't render with the following error:

[Error] SyntaxError: Invalid regular expression: invalid group specifier name
	(anonymous function) (asciidoctor-kroki.js:18656)

Thanks for help in advance

Safari does not support lookbehind in regular expressions (sigh): https://caniuse.com/js-regexp-lookbehind

To accommodate Safari we should rewrite this regular expression to avoid using lookbehind. It might require to do additional checks.

@romkavt The line number does not correspond but the error tells me that this is related to a regular expression. Do you have a more complete stacktrace ?

@Mogztter can we get this fix for Safari merged in?

@secdim If you could confirm that #228 actually resolves this issue in Safari that would be helpful. I don't have Safari so I can't make sure that my fix is sufficient.

I merged this 'by hands' in our installation and I confirm the fix works well on Mac OS Safari.

Yes, I have tested it and it fixes Safari issue.
