[23.1] Fix url_for in tool error reports

[davelopez]

Partial backport of #17058 to 23.1

Reported by @natefoo on Matrix:

Bug reports on .org are suddenly sporadically failing url_for here:

galaxy/lib/galaxy/web/framework/__init__.py

Line 21 in 573b902

return DEPRECATED_URL_ATTRIBUTE_MESSAGE

meaning the error report emails have no links
I haven't figured out yet under what conditions it works (that it's sporadic like this is weird enough).

How to test the changes?

(Select all options that apply)

• I've included appropriate automated tests.
• This is a refactoring of components with existing test coverage.
• Instructions for manual testing are as follows:
