CS8063 - Improve wording

Discussed in #67523

This has been bothering me for some time:

The message reads 'text' may be null here.

This is not really good English because 'may" means optional, permissible, something one could choose to allow, rather than undesirable, to be avoided, so this should really be changed to: 'text' might be null here.

This might be particularly confusing to non native English speakers too.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Moved to issue. Wrt to the request here, i think either is fine, but 'may' seems more correct to me. This is discussing things in the present tense, not past or past-perfect tense, so 'may' is more appropriate. WRT probability, both are ok as we are not claiming anything about high/low probability (so either would be fine). Given that, i would personally keep as 'may'.

However, i'm fine seeing what others think wrt to grammar here as to if this can/should be improved.
