Wrong priority for shift operators in pretty-printer

[verytactical]

Are you using the latest released (or pre-released, a.k.a. "next") version?

• I'm using the latest Tact version

Tact source code

contract Test {
    a: Int;

    init() {
        self.a = (1 << 2) + 3;
    }
}

Relevant Tact/build system log output

contract Test {
    a: Int;

    init() {
        self.a = 1 << 2 + 3;
    }
}

What happened?

getPrecedence doesn't have a case for << or '>>', and their priority is inferred to be 11, while by the grammar it should have been 7.5.

After printing the code self.a is set to 32, while previously it was 7.

What did you expect?

Pretty-printer should not change behavior.
