Install if frontend command exist

[dermatz]

Could not run/install command ddev frontend init if "frontend" command already exists.

It throws the error:

NOT overwriting .ddev/commands/web/frontend.
The #ddev-generated signature was not found in the file, so it will not be overwritten.
You can remove the file and use DDEV get again if you want it to be replaced: signature was not found in file .ddev/commands/web/frontend 

So it's by design and I think we should not interfere with it. 😕

Apparently the frontend has been modified by the user, since the original has #ddev-generated in it:

https://github.com/dermatz/ddev-woodoo-buildtools-magento/blob/main/commands/web/frontend#L2

So if you don't care about the modifications, just remove that file and a ddev get will work without errors.
