Fix other CSS macros after the CSS reorganization

[dipikabh]

Noticed in the Flaws reported in mdn/content#42346.

• The following broken links and redirects are coming from csssyntax macro:
  (MDN pages for Value definition syntax and @container)

One of the lines in csssyntax is:

"/{}/docs/Web/CSS/CSS_values_and_units/Value_definition_syntax"

which needs to be updated to /{}/docs/Web/CSS/Guides/Values_and_units/Value_definition_syntax.

• The following broken links are coming from the cssinfo macro (MDN page for fallback):

Basically, all instances of "/en-US/docs/Web/CSS/CSS" in rari need to be updated to reflect the new CSS directory structure.

• The other part of the issue about these flaws is that they are currently not reporting the macro name.
