Subject: [PATCH 2/6] Build inets charlists without single-quoted literals

Single-quoted charlist literals are deprecated on modern Elixir, and
the ~c sigil is unavailable on Elixir 1.8. String.to_charlist/1
compiles warning-free on every supported version.

Subject: [PATCH 4/6] CI: test legacy (hackney 1.x) and modern (hackney 4.x)
 dependency sets

Legacy Elixir/OTP entries move into hexpm/elixir containers because
erlef/setup-beam can no longer install OTP < 24.2 on current
GitHub-hosted runners. A new Elixir 1.19/OTP 28 entry exercises the
default lockfile with hackney 4.
