collections.EchoParam does not return boolean values #11498
Description
[params.footer]
string = 'foo'
int = 42
float = 3.1415
bool = true
{{ echoParam .Site.Params.footer "string" }} --> foo (string)
{{ echoParam .Site.Params.footer "int" }} --> 42 (int64)
{{ echoParam .Site.Params.footer "float" }} --> 3.1415 (float64)
{{ echoParam .Site.Params.footer "bool" }} --> "" (string)
...or deprecate the function. I'm not sure why we need three ways to do the same thing:
{{ site.Params.footer.key }}
{{ index site.Params.footer "key" }}
{{ echoParam .Site.Params.footer "key" }} <-- and with this one you need to lowercase the key, just like isset
