Consider making the `checkSuspiciousEnumValue` report a warning instead of an error

[markvl-sbp]

Whenever there is a number in an enum value, the linter reports an error (Enum '%s' has suspicious value '%s' (line %d)). This may be suspicious, but is it really an error?

Could you consider making this a warning instead?

Example:

"Enumeration of Citroen car models."
enum Citroen {
  C3
  C4
  C5X
}

Result:

ERRO[0000] ERROR: Enum 'Citroen' has suspicious value 'C3' (line 13)
ERRO[0000]   Did you mean 'ID'?
ERRO[0000] ERROR: Enum 'Citroen' has suspicious value 'C4' (line 14)
ERRO[0000]   Did you mean 'ID'?
ERRO[0000] ERROR: Enum 'Citroen' has suspicious value 'C5X' (line 15)
ERRO[0000]   Did you mean 'ID'?
