Add a pipe separator option for Multiple items format

In case its of use to others, for now I've added a pipe option to the functions formatHtmlItems and formatTextItems in WebformElementBase with this patch.

Please fix the spacing in the patch and provide test coverage.

Is that patch made with something besides Git?

Also: you probably don’t need to test every platform combination at this stage.

Thanks cilefen. I just used diff.

The patch failure message is error: Plugin/WebformElementBase.php: No such file or directory

Comparing a patch generated with Git its very similar to this one but with a/ b/ prefixes indicating the modified files. eg.

--- a/src/Plugin/WebformElementBase.php	2023-03-27 17:30:04.067928500 +0100
+++ b/src/Plugin/WebformElementBase.php	2023-03-27 17:38:59.712840100 +0100

I could amend the patch accordingly and upload again?

I just realized you could use custom Twig for pipe delimited values.

See attached the webform and below is the example Twig.

{{ items|join(''|'') }}
