Update trackdown now on cran

[ClaudioZandonella]

Hi @cderv,

Sorry for the time it took me to send this PR to update the old PR (#348) but it was a really busy month.

Now, the trackdown package is on CRAN (link). I have updated the information to install the package.
Note that I had to update the version of other packages as well because they are trackdown dependencies. In particular,

• cli 3.0
• gargle 1.2
• googledrive 2.0

Moreover, regarding the issue on write_bib() (knitr/issues/2028), the url is still missing from the reference because:

• although the package is now available on CRAN, the package is actually installed from the RSPM repository using install.packages(). This happens automatically probably for some default settings. As a consequence, the following code is not evaluated

https://github.com/yihui/knitr/blob/d65b9239804163b693cbfa4b774980f3b7d1fecd/R/citation.R#L75-L80

• if I update knitr to the development version, the code below will process the first url but the url is still set in note = and not in url = (as you already pointed out link). The note field is not printed in the reference.

https://github.com/yihui/knitr/blob/d65b9239804163b693cbfa4b774980f3b7d1fecd/R/citation.R#L102-L105

In the PR I did not updated knitr to the development version to avoid installing through GitHub. Let me know if you prefer I update it.

Thanks for your work!

Thanks!

Yes I see the issue with write_bib(), maybe it needs to support RSPM explicitly. I'll look into it.
