    tokeninfo: fix null pointer crash in tokenDelete function

    The tokenDelete() function in main/tokeninfo.c was being called with NULL
    pointers from the R6 parser error handling code, causing segmentation faults.

    The R6 parser in parsers/r-r6class.c had a comment stating "tokenDelete
    accepts NULL" but the function did not actually handle NULL pointers safely.
    This occurred when parsing malformed R6 syntax such as:
    - R6::SomethingElse() (wrong function after R6 namespace)
    - R6:: (incomplete namespace reference)
    - R6::R6Clas() (typo in R6Class)

    The fix ensures ctags handles malformed R6 syntax gracefully by falling back
    to parsing assignments as regular global variables instead of crashing.

      Fixes segmentation fault when processing certain R6Class syntax patterns.

    fixup! C++: Update the parser version to 2.2

    In d469bf986acc7837514680434e90bc6087fe2827, I forgot to update
    versionCurrent and versionAge member of the parser.

    (This means the parser versioning of ctags-6.2 is broken.
    I must backport this change to ctags-6.2 and release 6.2.1.)
