[ER Diagram] Use readable syntax instead of pictogram

Is your feature request related to a problem? Please describe. I’m always frustrated when writing er diagram using ‘||–o{’

Describe the solution you’d like Using ‘one to one’/‘one to many(1)’/‘many(0) to many(0)’ instead of '||--||'/'||-|{'/'}o--o{' or something better.

Describe alternatives you’ve considered I just want a readable syntax

Additional context I love all diagram except er. Thanks all contributors.

Using 0+ or 1+ instead of zero or more maybe more concise. Whatever, thank you for your contribution.

okay, I added these aliases too.

    T4 0+ to 1+ T6 : test
    T1 1 to 1 T3 : test
