Brand Refresh - Revisit content accuracy

[taysea]

The following sections of the site should be revisited to assess the accuracy of their content with respect to v5 of the theme:

• [ ] Confirm "Our Brand" content accuracy/if this content is up-to-date
• [ ] Adjust "Green color accessibility" documentation to clarify that "light" and "dark" green should only be used for "status"? Maybe add content about need for minimum of 19px and bold and #FFFFFF for text on HPE brand green.
• [ ] Button icons content feels out of place and unnecessary, proposing we remove: https://design-system.hpe.design/foundation/icons#button-icons
• [ ] Fix stack example (or remove content since button "badge" is recommended for this pattern?): https://design-system.hpe.design/components/stack
• [ ] Only "end truncation" (browser default) is supported. Should we remove other truncation types? https://design-system.hpe.design/components/datatable#options-for-positioning-truncation
• [ ] Assess accuracy of Tabs alignment content (I don't believe justify="start" is necessary anymore: https://design-system.hpe.design/components/tabs#alignment
