fix: 🤔 sd-tags paired with floating labels should always be size 'sm'

[martascorreia]

Current behavior

When using the sd-tags inside the sd-combobox and sd-select with floating labels enabled, the tags take the size set for the components.

Expected behavior

The sd-tags when paired with floating labels should always be size small 'sm', independently of the size of the component, to ensure the height of the overall component stays the same.

The documentation section 'Multiple' in both and 'Use Tags' in sd-select should also inform the user that sd-tags are always small.

Steps to reproduce

1. Go to SDS Storybook -> sd-combobox
2. Go to the Screenshots -> SizexMultiple
3. You can see the examples for the floating labels use lg and md size tags because these are the sizes set to the component, instead of always sm.
