Fix errors in en/de/pt-br

[hachi8833]

I have translated the repo to Japanese and found the following small errors.

• bitwise operators are inversed: ( see https://github.com/vlang/v/blob/master/vlib/v/token/token.v#L201 )

## Bitwise Operators

- `<<` left bitshift        -- should be `>>`

- `>>` right bitshift     -- should be `<<`

• missing ::

mut even_numbers = [2, 4, 6, 8, 10]      // `=` should be `:=`
even_numbers.delete(3)
println(even_numbers) // [2, 4, 6, 10]

The errors have been propagated to other locales partiall: de/pt-br/id. I fixed them as well.

I'd be glad if you'd merge this before I send the ja translation.

Thank you,
