comma should be period in cite_r footnote

[HeatherUrry]

Hello! I noticed that specifying footnote = TRUE in the cite_r function yields a comma instead of a period at the end of the sentence citing R. I traced it to the line referenced below.

papaja/R/cite_r.R

Line 137 in 7591bf3

res$pkgs <- paste0("\n\n[^papaja_pkg_citations]: ", apa_terms$cite_r_footnote, " ", pkg_info, ".\n\n")

Here's a screenshot showing an example in a knitted pdf:

Shall I submit a pull request to replace the comma with a period or is posting this issue sufficient? Thank you! And happy new year.
