Making a new revision on hackage

For example, these were the steps to make revision 3 of 1.0.3.1, bumping the upper bound on base to < 4.16 for GHC 9.0.1:

On branch master:
- haskell-src.cabal:
  1. bump base dependency's upper bound to < 4.16
  2. update tested-with field to include GHC == 8.10.4 and GHC == 9.0.1
- changelog.md: add entry for 1.0.3.1 Revision 3
- attic/haskell-src-1.0.3.1-r3.cabal
  1. create this file as a copy of attic/haskell-src-1.0.3.1-r2.cabal
  2. increase x-revision to 3
  3. bump base dependency's upper bound to < 4.16
  4. update tested-with field to include GHC == 8.10.4 and GHC == 9.0.1
- commit all that
- push (or do this in the very end)

Perform the revision on hackage:

review the revision:

hackage-cli push-cabal attic/haskell-src-1.0.3.1-r3.cabal

make the revision:

hackage-cli push-cabal --publish attic/haskell-src-1.0.3.1-r3.cabal

On branch 1.0.3._:

pull revision from hackage

hackage-cli sync-cabal haskell-src.cabal
