chore: improve bug report template with log toggle

[HonkingGoose]

Changes:

• Contributors can now put their logs behind a nice "Click me to see logs" toggle

Context:

It's easy to post a "wall of text" log into a bug report, this results in a lot of scrolling for other contributors/maintainers.
I found out that you can "wrap" your log into a <details> + <summary> tag, so that it expands when you click on the text.

I think it's a good idea to provide the HTML needed to do the right thing the first time round, as that reduces friction for all involved.

Related to PR #9242.

@rarkins Do you want me to put this text into this PR, to replace the current debugging help for self-hosted?

If you're running self-hosted, run with `LOG_LEVEL=debug` in your environment variables and search for whatever dependency/branch/PR that is causing the problem.

@rarkins Do you want me to put this text into this PR, to replace the current debugging help for self-hosted?

Maybe instead we link to our debugging guide and say something like "make sure you are capturing debug logs"?

[HonkingGoose]

I'm not sure what the "debugging guide" you're talking about is? Can you maybe explain more?

I found this:

• https://github.com/renovatebot/renovate/blob/master/docs/development/local-development.md#debugging
• https://github.com/renovatebot/renovate/blob/master/docs/development/local-development.md#log-files
• https://github.com/renovatebot/renovate/blob/master/docs/usage/self-hosting.md#logging

Those 3 seem somewhat relevant, but I'm not sure if either of those are what you mean when you say "debugging guide".

[rarkins]

I was probably misremembering the local developing debugging guide. We can merge this PR as-is once you're happy with it

[HonkingGoose]

@rarkins I'm happy with this, lets get it merged. 😉
