Set default %printer for NODE nterms

Before:

```
Reducing stack by rule 639 (line 5062):
   $1 = token "integer literal" (1.0-1.1: 1)
-> $$ = nterm simple_numeric (1.0-1.1: )
```

After:

```
Reducing stack by rule 641 (line 5078):
   $1 = token "integer literal" (1.0-1.1: 1)
-> $$ = nterm simple_numeric (1.0-1.1: NODE_LIT)
```

`"<*>"` is supported by Bison 2.3b (2008-05-27) or later.
https://git.savannah.gnu.org/cgit/bison.git/commit/?id=12e3584054c16ab255672c07af0ffc7bb220e8bc

Therefore developers need to install Bison 2.3b+ to build ruby from
source codes if their Bison is older.

Minimum version requirement for Bison is changed to 3.0.
