[Feature Request] Add make target to start a development env with database and air hot loading

Tell us about your feature request

Currently there is no make target that enables me start the database together with air hot loading. Either I can use make docker-run which does not support air hot loading, or I can use make watch which does not start the database. I'd like to be able to start a development environment that supports both a database (as a test container like used for the tests or a regular docker image) together with the server with air hot loading support.

We can approach the solution in two different ways. One would be to simply add a target to the Makefile so that when make watch is executed, the database is also spun up:

watch:  docker-run
       @if command -v air > /dev/null; then \
	    air; \
	    echo "Watching...";\
        ...

Alternatively, we can achieve this using a Dockerfile and Docker Compose: (This is just a code snippet to demonstrate the concept, the database part is not included.)

FROM golang:1.22-alpine AS base

RUN apk add --no-cache make

WORKDIR /app

COPY go.mod go.sum ./
RUN go mod download

COPY . .

FROM base AS dev
RUN make build
EXPOSE 5000
CMD [ "sh", "-c", "echo 'y' | make watch" ]

FROM base AS build
RUN make build

FROM alpine:3.20.1 AS prod
WORKDIR /app
COPY --from=build /app/main /app/main
EXPOSE 5000
CMD ["./main"]

services:
  web-dev:
    build:
      context: .
      dockerfile: Dockerfile
      target: dev
    ports:
      - 5000:5000
    volumes:
      - ./:/app

  web-prod:
    build:
      context: .
      dockerfile: Dockerfile
      target: prod
    ports:
      - 5000:5000

# docker compose up  web-dev --build
# docker compose up  web-prod --build

There is also a compose watch option that could be considered as an alternative.

It is a nice issue to solve, so any PRs are welcome.
