[Hotfix]: Make alttext work for cover image and when pandocbounded is not present

[Schiano-NOAA]

What is the feature?

• Adjusts the method from pdftooltip to pandocbounded for alt text in the cover page
• Instead of removing lines that do not have pandocbounded or tooltip, the function just removes the line for the artifact since this is the only known line there that has alt text

How have you implemented the solution?

• change format to the alt text in the cover page to match that in add_alttext
• Remove the loop that id's which images don't have pandocbounded and instead id the line that has the artifact

Does the PR impact any other area of the project, maybe another repo?

• no

Pull request overview

This hotfix addresses alt text handling for cover images and figures that don't have the pandocbounded wrapper in LaTeX documents. The changes unify the alt text format and simplify the logic for identifying which figure lines need alt text processing.

• Updated cover page alt text from pdftooltip format to pandocbounded format with inline alt= attribute
• Replaced loop-based filtering logic with direct artifact line removal to handle figures without pandocbounded

Looks good! I'm not sure why only the mac R Cmd check is failing, but that happened to me last week and eventually it disappeared.

@sbreitbart-NOAA great! I'm going to push a check for the artifact then merge after checks
