sub-issue of #10698 according to @sholderbach
(Description largely edited, since the scope of the PR changed)
# Description
Context: `ShellError::OnlySupportsThisInputType` was a duplicate of
`ShellError::PipelineMismatch`
so I
- replaced some occurences of PipelineMismatch by
OnlySupportsThisInputType
For another PR
- replace the remaining occurences
- removed OnlySupportsThisInputType from nu-protocol
# User-Facing Changes
The error message will be different -> but consistent
# Tests + Formatting
OK
# After Submitting
Nothing required
