Using mix phx.new with --no-html still configures live_view in test config

[pcapel]

Environment

• Elixir version (elixir -v):
  Erlang/OTP 26 [erts-14.0] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]

  Elixir 1.16.0 (compiled with Erlang/OTP 26)

• Phoenix version (mix deps):
  {:phoenix, "~> 1.7.12"}

• Operating system:
  MacOS Sanoma 14.4.1

Actual behavior

Running mix test fails because config/test.exs contains a configuration for :phoenix_live_view which isn't installed under the --no-html flag. The offending block is:

config :phoenix_live_view,
  # Enable helpful, but potentially expensive runtime checks
  enable_expensive_runtime_checks: true

Expected behavior

Running mix test passes all pre-configured tests immediately after project generation.
