[alg.equal] Wrong wording (by copy/paste?)

[lynnboy]

At [alg.equal]/3.2, the case should be "For the overloads with ExecutionPolicy," the "no" should be removed.

The wording was added here:

151449b#diff-55a2410a80cb8710b07b579048668170R2104

@AlisdairM: Could you please check and advise?

@zygoloid: This looks like a misapplication of P0467r2.
