axa-fieldset: wrong breakpoint after migration

[domirs]

the axa fieldset stretch option is not working properly since #2296 due to inproper replacement of @include breakpoint($mediaquery-xs) { with @media (min-width: $breakpoint-xs) {

Expected Behavior

Current Behavior

Possible Solution

replace @media (min-width: $breakpoint-xs) { with @media (max-width: $breakpoint-xs - 1) {

the top-content-bar could potentially have a similar issue: https://github.com/axa-ch-webhub-cloud/pattern-library/pull/2296/files#diff-91cd5bc5cb5105781a58fc7b1b7325efb9146f329740a99b63b78b76929bdcbeR131
