[Conventions] List of code values: remove comma ?

[smnandre]

When listing code values, I believe omitting commas could significantly enhance readability.

Although it might be slightly less correct from a syntactical standpoint, I think the trade-off is worthwhile.

Example there: https://symfony.com/doc/current/reference/formats/yaml.html#booleans

with	without

WDYT ?

Yes, I agree. A single whitespace to separate chars looks better than a comma.

But, let's wait for more opinions before doing any change. Thanks.
