[bug] title style fixes

[marionnegp]

Describe the bug

Heading styles from a constructed stylesheet are preventing titles in some card patterns from being consistent with what's in Figma. Some of the computed values end up being correct, but since these titles use --rh-font-family-body-text, the following css uses body-text tokens for the other text properties too. (I think that's what we typically do.)

• Asset card titles should be using:

font-family: var(--rh-font-family-body-text, RedHatText, 'Red Hat Text', Helvetica, Arial, sans-serif);
font-weight: var(--rh-font-weight-body-text-regular, 400);
font-size: var(--rh-font-size-body-text-md, 1rem);
line-height: var(--rh-line-height-body-text, 1.5);
color: var(--rh-color-text-brand-on-light, #ee0000);

• Title bar cards should be using

font-family: var(--rh-font-family-body-text, RedHatText, 'Red Hat Text', Helvetica, Arial, sans-serif);
font-weight: var(--rh-font-weight-body-text-regular, 400);
font-size: var(--rh-font-size-body-text-md, 1rem);
line-height: var(--rh-line-height-body-text, 1.5);
