Document how to set the language used by glosario in Rmd document headers

[beatrizmilz]

The function gdef() generates the link to the term in glosario in the page in english.
For example:

`r glosario::gdef('tidyverse', 'tidyverse')`

The link created is: https://carpentries.github.io/glosario/en/#tidyverse

Can we have an argument lang , so the function could create a link to pages in other languages?

Reference of the function:

Thank you!

Hi @beatrizmilz,

The documentation needs to be improved here. For now, this function reads the metadata from the Rmarkdown file hearder to select the language.

so if your RMarkdown document has:

---
glosario:
   language: 'pt'
---

in its header, the definitions will be displayed in Portuguese.

That being said, having a per-definition language selector might also be helpful.

It worked! Thank you so much @fmichonneau !

If that's ok, I can try to make a PR and add this information on documentation.
This is the file, right?
