feat: append spinner in the end when --info=inline

[phanen]

Since all other infoStyle has spinner, maybe also add spinner for --info=inline.

Not sure if $FZF_SPINNER should be exported (#4344 (comment)). Or just export idx of spinner, so user can use their custom one.

I'd hold off on the decision until someone actually asks for it (seems unlikely).
