Entity generation fails if `model-extra-attributes` include a comma surrounded by parentheses about sea-orm

[yexiyue]

I also encountered the same problem

sea-orm-cli generate entity   -o entity/src -l -u postgres://postgres:postgres@localhost:22732/postgres 
--with-serde both  
--model-extra-attributes='graphql(concrete(name = "Favorite",params()))' 
--model-extra-derives async_graphql::SimpleObject

result

yexiyue@wisteriadeMacBook-Pro graphql-study % sea-orm-cli generate entity   -o entity/src -l -u postgres://postgres:postgres@localhost:22732/postgres --with-serde both --model-extra-attributes='graphql(concrete(name = "Favorite",params()))' --model-extra-derives async_graphql::SimpleObject

When I remove the comma before params, it can work properly

However, there are still spaces in front, which is not very aesthetically pleasing
