Highlight color of `LspSigActiveParameter` is probably not appropriate.

I use onedark as the theme for vim, I found that the color of LspSigActiveParameter is gray that I can barely see it.

After some research, I found out that the color is linked to LineNr:

hlset([{name: 'LspSigActiveParameter', default: true, linksto: 'LineNr'}])

Many users use a dark theme for vim and the color of LineNr is gray, so I thought that linking LspSigActiveParameter to LineNr may not be a good idea.

Additionally, I think that linking LspSigActiveParameter to Special may be good (at least in my case) and the color is blue in onedark theme.

You can override the highlight groups used by the plugin. In your .vimrc file, before adding the plugin, you can define the highlight group:

   highlight link LspSigActiveParameter Special

In my local Ubuntu setup, I see that the LineNr highlight group is using the Yellow foreground color and on MS-Windows, it is using Brown. Are you using a color scheme, that changes this highlight group?

Yes, onedark changes the color of LineNr and I think that's good, because most users don't need a highlighted color for line number, but they need a highlighted color for LspSigActiveParameter. What I mean is that linking LspSigActiveParameter to LineNr is not appropriate for many users who're using a dark theme and not appropriate semantically.

I could change this in my vimrc, but I still think it's a better idea to link to Special. However, it's up to you.
