This PR was squashed before being merged into the 3.x branch.
Discussion
----------
Support underscores in number literals
```twig
{{ 1000 == 1_000 ? 'yes' : 'no' }}
# now: syntax error
# this PR: "yes"
```
> As of PHP 7.4.0, integer literals may contain underscores (_) between digits, for better readability of literals. These underscores are removed by PHP's scanner.
https://www.php.net/manual/en/language.types.integer.php
This PR replicates that behaviour, using the regexp to match the literals and then remove the "_".
I'm targeting **Twig4** but maybe 3.x would be ok?
I cannot think of a real case that
- does not trigger an error currently
- would work differently after this PR
