bug: Making a project inside a folder name with a # will throw "invalid container name" when using start-database.sh

Provide environment information

NOTICE: I discovered that using a # in a folder name will trip out react and it will not be able to find any modules. Sorry about the issue bloat. I got ahead of myself.

System:
OS: macOS 14.4.1
CPU: (12) arm64 Apple M2 Pro
Memory: 85.20 MB / 16.00 GB
Shell: 5.9 - /bin/zsh
Binaries:

Describe the bug

When creating an app with create-t3@latest inside a folder name with # will throw an "invalid name in container" error when using the

bash start-database.sh

script command. This is a valid issue for database container names. The special characters allowed in creating an app are '-' and '_' but that is only restricted when creating a new folder with the cli. This feature does not exist when you use the dot method when creating a new app directly in the parent folder.

Command line error:
bash start-database.sh
docker: Error response from daemon: Invalid container name (bug#1847-postgres), only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed.
See 'docker run --help'.

Reproduction repo

https://github.com/xelacast/issue-1834

To reproduce

either pnpm create t3-app@latest inside a folder with a hashtag # in the name and do not specify a name. Then bash start-database.sh.

or

clone the repo.

git clone git@github.com:xelacast/issue-1834.git && bash start-database.sh

Another error occurs when you use the command the pnpm create t3-app@latest . command. The container name will be initialized to '.-postgres' and error with:

Error response from daemon: No such container: .-postgres
Error: failed to start containers: .-postgres
Existing database container '.-postgres' started

Additional information

If this is a valid bug, I propose to change how the container name is created for the start-database.sh file and find any invalid characters and change them with '-' or remove the space to improve the UX of the database startup process. Github removes invalid characters for repos and replaces them with the '-'. This happened for my reproduction repo name.

I'd appreciate the opportunity to implement this small feature. Thank you T3 team for creating a great tool!
