Fix/1238 adjust organization card height

[MarcoRehmer]

What and Why

• increase the height of organization cards to 390px fix

Additional

• add "husky" pre-commit hooks and "lint-staged" to only format staged files with prettier (only affects js, ts, jsx, tsx files. Backend files are not be affected by this)
• add installation steps to README.md

For the the husky pre-commit hook doesn't work yet.
I ran the sh yarn preparecommand in climateconnect/frontend. This creates a climateconnect/frontend/.husky/pre-commit file which looks like this:

#!/usr/bin/env sh
. "$(dirname -- "$0")/_/husky.sh"
cd frontend && npm run pre-commit

When making a commit it will fail because this file is in the frontend folder but tries to cd to frontend which is not possible because it's already there so I get this error: frontend/.husky/pre-commit: 5: cd: can't cd to frontend

Also yarn prepare creates a file named .yarn-integrity. We should either commit this file or add it to .gitignore.

ah yes good catch, also it should not run "npm", instead yarn should be used. I will fix that
