More Password Generator options

[Robin481]

Instead of just having the option for a random password that is always 14 characters long we would like to have it more configurable.

Options should be:

• Length of the randomly generated password (up until 32 characters)
• Whether the password contains special characters or not

Additionally we should evaluate whether we are using a proper random generator or if we should switch to something more secure. From a short glimpse we use Math.random which according to: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random should not be used for anything security related.

ToDo:

• Draw a Mockup for the design to make it clear how it should look when it is done
  • Check with UX/The team whether this seems reasonable
• Replace Math.random with something secure like https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues
• Create the inputs that allow the user to determine which options are selected when creating the random password.
• Tests 🥳
