Fix warnings in core libs revealed v0.14.1 PS release #4071

Now that v0.14. is out, we should fix any of the warnings found by the update in core libs. This issue tracks which of them need that and whether a PR has been submitted/merged yet. A checked box below means a PR has been submitted (but not necessarily merged). See methodology below for how this list was produced.

• arrays
• catenable-lists
• datetime
• filterable
• foldable-traversable
• foreign
• free
• functors
• lists
• ordered-collections
• prelude
• quickcheck
• st
• tailrec
• transformers
• tuples

Method for producing the above list:

1. Created a new project using spago init
2. Manually updated packages.dhall file to update metadata.version = "v0.14.1"
3. Ran spago install $(spago ls packages | cut -f 1 -d ' ' | tr '\n' ' ') to install all packages in the set
4. Ran spago build --purs-args "--censor-codes='UserDefinedWarning'". I was trying to stop MonadZero deprecation notices from being include din list of warnings. I don't think this worked because censor-codes likely only works on source code defined in the src/ directory, not the .spago/ directory.
5. Copied shell's output that listed all warnings into file called fix-warnings-source
6. Ran cat fix-warnings-source | grep '.spago/' | cut -f 3 -d ' ' | cut -f 2 -d '/' | uniq > fix-warnings.txt (record a list of deduplicated packages that have a warning in them)
7. Copied and pasted data into Excel file
8. Ran spago ls packages | grep '/purescript/' | cut -f 1 -d ' ' > purescript.txt to get a list of all core repos
9. Ran spago ls packages | grep '/purescript-contrib/' | cut -f 1 -d ' ' > purescript-contrib.txt to get a list of all contrib repos
10. Pasted purescript.txt and purescript-contib.txt into Excel fil
11. Used VLOOKUP Excel formula to find all purescript and purescript-contrib libs that had warnings.

This likely isn't the best method for determining things, but seems like it's likely 90% right.
