Incomplete and/or invalid BS5 components

[WinterSilence]

Same problem as in package yii2-bootstrap5, that's widgets generates not complete or invalid BS5 components.
For example, simplest component in BS5 - buttons, widget Button not implements:

• <a>s don’t support the disabled attribute, so you must add the .disabled class to make it visually appear disabled
• Disabled buttons using <a> should include the aria-disabled="true" attribute to indicate the state of the element to assistive technologies
• Disabled buttons using <a> should not include the href attribute
• <a> should be given a role="button" to appropriately convey their purpose to assistive technologies

basic HTML generator's features:

• auto escape content (escape only if not contains < and >)
• normalize attribute values (boolean attributes set as "" or "attribute" too)

too not implemented...

What's doing widget? Add class btn and and generate tag i.e.

echo Button::widget()->label('Action')->options(['class' => 'btn-lg']);

generates

<button class="btn btn-lg">Action</button>

HTML tag less than PHP code!
This shows that dummy-widgets like as Button are useless to generates BS5 components.
