all: use modern Go syntax (e.g. any instead of interface{})

[abhinav]

This change was generated by running:

go run golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest -fix -test ./...

Two things are changed:

• All interface{} types are changed to any.
  This has been available since Go 1.18.
• Stops capturing loop variables for closures inside loops.
  This has been unnecessary since Go 1.22.
