[GNC] the url "ghelp:gnucash-guide" does not point to a valid page, Ubuntu 22

[Tom Balazs]

When I click Help / Tutorial and Concepts Guide I get the error message
"The URI ‘ghelp:gnucash-guide’ does not point to a valid page."

When I search my hard disk I
see /usr/share/doc/gnucash-docs/gnucash-help-en/ which has the "GnuCash
Help Manual" in it, in HTML format.

How do I fix this link so that it works like it should?

I'm on Ubuntu 22.04.3 LTS.
