v0.50.2

This is a bug fix release that addresses a regression in 0.50.1.
This regression impacts policies with rules that, as its else-value, assign a comprehension containing variables.
Such rules would cause the compilation of the policy to fail with a rego_unsafe_var_error error.

E.g. the following policy would fail to compile with a policy.rego:5: rego_unsafe_var_error: var x is unsafe error:

package example

p {
	false
} else := [x | x := 1]
