Fix autocomplete suggestions for repository of type fs (typo)

[yuliacech]

Summary

While investigating alternative solutions for #120512 I noticed that autocomplete suggestions for repository settings of type fs were not working. Other repository types have autocomplete suggestions for settings.
NOTE: I'm not sure why, but template autocompletion (the default object printed out when settings is selected) is always the template for type fs.

Thanks for patching this up @yuliacech! Changes make sense, tested locally and all works as expected 🚀

I also experienced the same problem in which the autocompletion for settings is always for fs, is there a bug open for that or should we open one?

Thank you for the review, @sabarasaba! I opened this issue #120888 for the template bug.
