Move document corner fold to top right in two icons
Summary:
This updates document-close in the sizes below 32px and gnumeric-link-internal to the new style. I forgot them in D28203.
gnumeric-link-internal uses Highlight, it had a fixed color before.
document-close uses NegativeText in all versions. The 16px dark version used Text before.
