make "upvote feature request" text clearer

[ultraGentle]

Currently, when vscode bot announces that a feature is a backlog candidate, there are two recurrent points of confusion:

1. Which post in the thread should be upvoted?
2. What is a "backlog candidate", and why should we care?

Proposed solution:

1. Add text to indicate that upvotes should happen on the first post
2. Instead of "backlog" which is jargon-y, use common terms, like "this is now a feature candidate. To be accepted..."

Side note: this is related to #89652, in that it is another example of how the current upvote system potentially introduces sample bias preferencing more sophisticated users. Separately from addressing that, though, the language here can be more inviting/inclusive.

Totally agree with this post, I have no idea how to upvote even if I managed (by chance!) to access the backlog candidate. I have reported an issue which is rather obvious, which has been reported already month ago, which is in the backlog candidate, and I just don't know how to upvote it, so basically if many people are like me, we'll be waiting for months or years for this to be taken into account, this is ridiculous guys...

@eliyo FYI, to upvote, simply click the thumbs up that appears on the first post of the thread.

Dear @eamodio and @kieferrm , any thoughts? As a small component of #89652, this one seems pretty unambiguously fixable by just a bit of textual clarification.

please address this so others don't have to waste time searching.

i see also i have a problem that the bot text and the documention is not cleare where to make the upvotes:

• is there a different voting system i am not aware of?
• where i have to click and what i have to do to have a "upvoting" get voted? because an github issue not have a voting feature.

and as i see in the closed issues with the backlog: there are many issues which have not even one smiley have on it - is there something wrong with the voting sytem or is it hidden to me.

It would be nice if it was possible to upvote closed feature-requests, or not close feature-requests at all, so that all feature requests have longer to accumulate votes. For example I would love to see #89901, but didn't see it before it closed. Surely there are lots of feature-requests that are only seen by people who'd upvote them, but can't because they only found them after they closed.

Came here from an issue thread that I needed to upvote, I now know how to, but it was not clear.
