Link Issue in Generated Content for Pages

[brian-ruf]

Describe the bug

On pages.nist.gov/OSCAL, in the schema map, when I click on Markup Multiline I receive a page not found error.

From the catalog schema map, the link for markup multiline attempts to open this page:
https://pages.nist.gov/OSCAL/documentation/schema/catalog-layer/datatypes/#markup-multiline

It should be opening this page:
https://pages.nist.gov/OSCAL/documentation/schema/datatypes/#markup-multiline

The difference is the incorrect inclusion of 'catalog-layer' into the URL.

UPDATE: This bug is also impacting the clickable data types on the schema reference page. Clicking "String" yields the same issue.

Who is the bug affecting?

Anyone using the OSCAL syntax reference to learn more about the datatype of any particular field.

What is affected by this bug?

Inability to cleanly obtain necessary information.

When does this occur?

Every time someone tries to follow a datatype link from the schema reference or schema map content.

How do we replicate the issue?

From Schema Map:

1. Visit this URL: https://pages.nist.gov/OSCAL/documentation/schema/catalog-layer/catalog/xml-model-map/
2. Click on any Markup Multiline reference in the schema map.

From the Schema Reference:

1. Visit this URL: https://pages.nist.gov/OSCAL/documentation/schema/catalog-layer/catalog/xml-schema/
2. Click on any datatype, such as "(String)" or "(NCName)".

If applicable, add screenshots to help explain your problem.}

Expected behavior (i.e. solution)

The link should take the user to a heading on the OSCAL datatypes page, based on the data type they clicked. For example:
https://pages.nist.gov/OSCAL/documentation/schema/datatypes/#markup-multiline
