Remove partial argument usage #6855

[Mukulyadav2004]

Closes #6855

This PR replaces partial argument names (id, fun.agg, measure) with their full names (id.vars, fun.aggregate, measure.vars) in the following vignettes for improved clarity and consistency:

->vignettes/data.table-reshape.Rmd
->vignettes/fr/data.table-reshape.Rmd
->vignettes/ru/data.table-reshape.Rmd
Additionally, these changes ensure better alignment with the surrounding text for improved coherence.

@MichaelChirico, please review when you have time. Thank you!

Tested by re-rendering with options(warnPartialMatchArgs=TRUE, warn=2).

Ideally, we remove partial arguments from all vignettes in one go, right?

[aitap]

There could be more in non-executable chunks, but in my tests, only data.table-reshape.Rmd previously failed with options(warnPartialMatchArgs=TRUE, warn=2).

You are right, I just manually build all vignettes with tools::buildVignette() and only the reshape vignette failed

[Mukulyadav2004]

I have removed partial matching in the reshaping vignette since it was causing build failures with options(warnPartialMatchArgs=TRUE, warn=2). The other instances in comments and tests are either intentional or not causing any issues.
I kept this PR focused on resolving that issue. However, I’m open to addressing partial matching in other non-executable chunks if needed.
