Issue

Documentation is unclear about requirements

• Requirements are missing git and gcc
• For git it is very trivial to be a requirement due to cloning the repository
• But without gcc the build.sh script is not failing or displaying good perceptible warnings / errors.
• On a fresh installed Debian 11 (5.10.0-11-amd64) I was able to run the build.sh but had no generate-keys nor dendrite-monolith-server in the bin folder.
• Running:

  go build -o bin/generate-keys ./cmd/generate-keys

• gave me the error, that no gcc was found in $PATH
• after installing gcc:

  gcc --version
  gcc (Debian 10.2.1-6) 10.2.1 20210110
  [...]

• and clone a new repository, running build.sh works as expected
• Unfortunately I not examine the gcc problem further, but as said, it was a fresh installation of Debian 11 <

  /usr/bin

• was definitly in $PATH

Expected behavior

• requirements should be clearer in documentation or the build.sh script should give more perceptible warnings / errors

If this is not wanted for a particular reason I can create a pull request and add git and gcc to the requirements but I'm not sure about the miniumum versions
