Documentation: useful commands for contributors

[kpodp0ra]

During my development, I used the following commands:

To update my database after git pull

/teable/packages/db-main-prisma$ pnpm  dotenv-flow -p ../../apps/nextjs-app -- pnpm prisma generate "--schema" "./prisma/postgres/schema.prisma"
/teable/packages/db-main-prisma$ pnpm  dotenv-flow -p ../../apps/nextjs-app -- pnpm prisma migrate "deploy" "--schema" "./prisma/postgres/schema.prisma"

To make a build

docker build . --file=dockers/teable/Dockerfile -t teable-fork

---

I am curious to know what commands @tea-artist uses and whether we should add them to https://github.com/teableio/teable/blob/develop/CONTRIBUTING.md and Makefile/package.json

Inspired by #1217

@kpodp0ra I updated the CONTRIBUTING.md and listed our commonly used commands. If there are more questions, you can raise them in this issue. I will update it if appropriate.
