Make missing plugin repo errors more informative

[dmytrovoytko]

Thank you for this great editor!
Please consider this update to handle missing plugin repo errors better.
It addresses #1276

Plugins in official channel are ok now (may change someday), but 3 plugins of unofficial channel are missing and it shows up as strange messages while running micro -plugin available or other plugin commands:

Failed to decode repository data:
 json: cannot unmarshal number into Go value of type config.PluginPackages
Failed to decode repository data:
 invalid character '<' looking for beginning of value
Failed to decode repository data:
 invalid character '<' looking for beginning of value

Instead it would show up like this:

Skipped: Plugin repository not found at https://raw.githubusercontent.com/cadnza/mxc/main/repo.json (Status Code: 404).
Skipped: Plugin repository not found at https://notabug.org/dustdfg/micro-calc/raw/master/repo.json (Status Code: 404).
Skipped: Plugin repository not found at https://notabug.org/dustdfg/micro-mdtree/raw/master/repo.json (Status Code: 404).

I think these fmt.Fprintf() logs might become quite long.
What about:

fmt.Fprintf(out, "Skipped: %s\n", pr)
fmt.Fprintf(out, "Reason: XYZ (Status Code: %d)\n", statusCode)

?

@Neko-Box-Coder:

Something to consider for your?

This is quite similar to one of my (forgotten) PRs.

The upstream for all those 3 are all gone/archived :(

It's an annoying error but any plugin actions are not affected (Apart from interacting from these 3 plugins ofc).
I will need to update the json for these plugins to point to my stable branch. I am slightly busy now but will try to sort it out asap.

Oh, damn.
Well, both have their own advantages. 🤔

To be fair, my PR was also doing something else.

We can merge this and I can adjust my PR.

My PR was also trying to do a reasonable timeout such that a git repo with very slow/unstable connection (notabug was one of them I believe, potentially codeburg as well) won't block the rest of the plugins.

Now it would look like this (better, thanks!)
