fix broken subscriptions

[Medium1992]

Hello.

Please ignore invalid links in subscriptions. People are really suffering and wondering why you are dropping the entire subscription when only a few proxies are invalid. Your position is partly understandable in terms of using normal subscriptions (#2128). But people are really suffering and don't understand why you can't just skip invalid links.
As a result, people create intermediate binaries on GO (https://github.com/Viktor45/sub-filter/) to filter subscriptions so that Mihomo will accept them, but why do that if Mihomo can do it itself?
There's no need to filter and correct anything, just don't add invalid ones.

I tried to assemble a test binary image.
The edit turned out to be in one line, but I just don't get why you can't allow invalid links to be skipped...

Yes, with the help of AI, I asked to patch it...
The result is that the subscription was added and invalid links were skipped...

Honestly, I just want to use your native compiled binary, so I ask you to change this behavior of the logic. Many will be grateful to you.

Here's what I tried to change in version 1.19.19, from dockerfile, and this work

RUN sed -i '/^import (/a\    "github.com/metacubex/mihomo/log"' \
    adapter/provider/provider.go

RUN sed -i 's@return nil, fmt.Errorf("proxy %d error: %w", idx, err)@name, _ := mapping["name"].(string)\n                log.Warnln("[Provider %s] skip invalid proxy (idx=%d, name=%q): %v", pdName, idx, name, err)\n                continue@g' \
    adapter/provider/provider.go

And I think you understand where to change what)
