Thanks for tackling this! Mind adding a quick test?

It's quick: add a new file with a hole, like this one:

https://github.com/haskell/haskell-language-server/blob/0905e682de8cc3e2bfe509313924cff0527b6791/plugins/hls-tactics-plugin/test/golden/GoldenArbitrary.hs

and then add the line, column and filename of the hole to this file:

haskell-language-server/plugins/hls-tactics-plugin/test/CodeAction/AutoSpec.hs

Line 74 in 0905e68

autoTest 25 13 "GoldenArbitrary"

running the tests will then generate the expected test output, and is good to check in.

Thanks so much!
