`wasp new` accepts invalid names

[infomiho]

wasp new prints these rules when a name fails:

The project's name is not in a valid format! The project's name:
  - must start with a letter or an underscore
  - must contain only letters, numbers, dashes, or underscores
  - must not be a Wasp keyword

But validation runs on the converted app name (kebabToCamelCase), which can repair violations - while the directory is created from the raw name:

$ wasp new -- -app     # converts to "App" -> passes validation
$ wasp new "app'"      # trailing ' allowed by identifier rule

Both proceed into template creation and leave shell-hostile directories behind:

🐝 --- Creating your project from the "basic" template... -------------------------
./-app

🐝 --- Creating your project from the "basic" template... -------------------------
./app'

Cause: parseWaspProjectNameIntoAppName validates the converted name (cli/src/Wasp/Cli/Command/CreateNewProject/ProjectDescription.hs:98) using isValidWaspIdentifier (src/Wasp/Analyzer/AST.hs:45), which also permits trailing ' primes the printed rules never mention.

Fix options: validate the raw project name against the printed rules as well, or extend the rules text to describe actual acceptance.
