What should I update to resolve RCurl SSL version issue

When I run a sample code

require(RCurl)
search_example <- postForm(
  "https://en.wikipedia.org/w/api.php", 
  action  = "opensearch", 
  search  = "Te", 
  format  = "json"
)

I get an error

Error in function (type, msg, asError = TRUE) : error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

I understand that it's not an issue of RCurl itself but rather of SSL library it is using - but what exactly should I update?
Notably, standard methods from utils work without errors:

url_https <- "https://en.wikipedia.org/w/api.php?action=opensearch&search=Te"
download.file(url_https, tempfile(),  method = "libcurl")
download.file(url_https, tempfile(),  method = "curl")

I'm under Windows 10 (Pro, 64-bit), R version 3.6.1, RCurl package version 1.98-1.2. RCurl::curlVersion()$ssl_version gives the following:
