fix(makefile): remove remove target dependency to dependencies target

[fffonion]

To preserve the previous behaviour.

This is a regression from #10442 and #10490.

Fixes https://github.com/Kong/kong-plugin/actions/runs/4421446482/jobs/7765323653

The previous dependency was:

install:
	@luarocks make OPENSSL_DIR=$(OPENSSL_DIR) CRYPTO_DIR=$(OPENSSL_DIR) YAML_DIR=$(YAML_DIR)

remove:
	-@luarocks remove kong

dependencies: bin/grpcurl
	@for rock in $(DEV_ROCKS) ; do \
	  if luarocks list --porcelain $$rock | grep -q "installed" ; then \
	    echo $$rock already installed, skipping ; \
	  else \
	    echo $$rock not found, installing via luarocks... ; \
	    luarocks install $$rock OPENSSL_DIR=$(OPENSSL_DIR) CRYPTO_DIR=$(OPENSSL_DIR) || exit 1; \
	  fi \
	done;

dev: remove install dependencies
