[Go] - FP on S1763 when a semicolon is added

As said in Go documentation on Semicolons:

Like C, Go's formal grammar uses semicolons to terminate statements, but unlike in C, those semicolons do not appear in the source. Instead the lexer uses a simple rule to insert semicolons automatically as it scans, so the input text is mostly free of them.

Thus the presence of a semicolon at the end of a statement does not mean that a statement follows.

The rule raises a False Positive when a jump statement is followed by a semicolon:

func fn(myvar int) int {
  return myvar; // False positive
}

The semicolon is superfluous but there is no dead code.

Note that there is a similar issue for RSPEC-122 (SONARSLANG-449)
