Steps to Reproduce

When you have dots in the TOML key names (for example, with the XSLT parameters in xslt.html), you can't set them.

Actual Behavior

The normal way creates a wrong output:

$ docbuild --set-env "xslt.html.show.edit.link=1" config list --env | sed '1,2d' | jq .xslt.html
{
  "show": {
    "edit": {
      "link": "1"
    }
}

Single quotes don't work:

$ docbuild --set-env "xslt.html.'show.edit.link'=1" config list --env | sed '1,2d' | jq .xslt.html
{
  "'show": {
    "edit": {
      "link'": "1"
    }
  }
}

Expected Behavior

The --set-env should handle quoted strings as one string and not separate:

$ docbuild --set-env "xslt.html.'show.edit.link'=1" config list --env | sed '1,2d' | jq .xslt.html
{
  "show.edit.link": "1"
}

Perhaps we should even go a little further and assume that the value of the key (here 1) is an actual integer, not a string. The output should be like this:

{
  "show.edit.link": 1
}

If we want a string, we need to quote that:

$ docbuild --set-env "xslt.html.'show.edit.link'='1'" config list --env | sed '1,2d' | jq 

or like this:

$ docbuild --set-env 'xslt.html."show.edit.link"="1"' config list --env | sed '1,2d' | jq 

Not sure if there is an easier way to do it.
