Ruby 2 docset not found

[tihnessa]

I have installed the Ruby 3 docset but when I try to go into it, I get an error

Error opening
/home/david/.local/share/Zeal/Zeal/docsets/Ruby_3.docset/Contents/Resources/Documents/standard_library_rdoc.html
No such file or directory

Removing and reinstalling makes no difference

The docset is present, just this one file is missing. There is a standard_library_md.html in the folder

And if I mv standard_library_md_html standard_library_rdoc.html all seems to be well
