Add minlength and maxlength to text field

[Pytal]

Add minlength and maxlength to be forwarded to the input by v-bind="$props"

The part which adds the autofocus prop definition is an addendum to #3245

Before this change autofocus wasn't contained in $props so it wasn't automatically forwarded by v-bind="$props", adding the explicit definition now makes it get forwarded by the v-bind and also makes the prop show up in the docs

Thank you! Looks much cleaner now 🧹
