Vscode-vsce: Support to ignore keyword list length warning

[joaomoreno]

With a VSCE_IGNORE_KEYWORD_LENGTH env variable.

From Microsoft/vscode#60214

VSCE_IGNORE_KEYWORD_LENGTH sounds like it has something to do about the number of characters used, maybe VSCE_IGNORE_KEYWORDS_LENGTH would be more appropriate 🤔.

Would be nice to see this and the 5 keyword limitation documentation with the keywords field

Also might be worth mentioning in the documentation that for more than 5 keywords we can use a comma delimited string like "cats, dogs, chickens". This is what I currenlty have to do for my extenstion

@pflannery I'm not sure how this is handled internally, but "cats, dogs, chickens" might just be considered a single tag.

[pflannery]

@fabiospampinato No they are handled as seperate "tags"

You can see it working on my extension page and here is the package.json

@pflannery interesting, it looks like you don't need to do that to get them displayed in the marketplace: see here and here. I wonder if the 5 keywords limit is actually implemented properly 🤔
