Allow everything but unicode emojis

[i-oden]

Description

We previously disallowed a lot of characters from specific fields and decided to go with basically the same thing for the project description. However, the Order Portal allows for all characters, and those using this often collect the order information and use this when creating the data delivery project. This causes the DDS to refuse the project because the description for example contains "invalid characters".

When looking at this I at first couldn't find what had been producing the errors before, but finally I realised that it's unicode characters and emojis that product SQLAlchemyErrors. In this PR I have changed the description validation to allow all characters except the unicode emojis/signs/characters etc.

I did a test in gitpod with "dds project create -t test -d "test project 😀" -pi [email protected]" and it worked as expected:
Current user: unitadmin_1
ERROR ⚠️ Failed to create project: This input is not allowed:
😀 ⚠️

Didn't run the tests locally, though
