Reimplement full width tables in PDF report

[jwalton3141]

{kableExtra} uses the LaTeX packages "longtable" and "tabu" to typeset tables which are "full width". However, the tabu package is broken and unmaintained.

This is a known issue, which can be tracked here: haozhu233/kableExtra#625

For now I've set full_width = FALSE, but the resulting tables are unsatisfactory.

Possible solutions might include

1. Setting \usepackage{longtable}[=v4.13] in inst/rmarkdown/templates/nata-report/resources/template.tex file (easy) and trying to get {tinytex} to install this older version of longtable (maybe not so easy...), or
2. Patching the raw LaTeX which {kableExtra} produces to use the tabularray package (https://tex.stackexchange.com/q/600724/181010 for more details)

A possible workaround could include using the column_spec() function with the width argument

Well, I'm pleasantly surprised: setting \usepackage{longtable}[=v4.13] in inst/rmarkdown/templates/nata-report/resources/template.tex did the trick, without necessitating any messing about with {tinytex} or installing historic LaTeX packages!
