vendor: update github.com/VictoriaMetrics/metricsql from v0.4.3 to v0.5.1

Browse source 
The new version of the package supports binary operations on string literals:

    * "foo" + "bar"     => "foobar"
    * "foo" == "bar"    => NaN
    * "foo" == "foo"    => 1
    * "foo" >bool "bar" => 1
    * "foo" < "bar"     => NaN
