std.clamp not declared in linter stdlib

[nate-thirdwave]

The function for std.clamp does not appear to be defined. Indeed when looking in linter/internal/types/stdlib.go there does not seem to be a definition for clamp.

jsonnet-linter deb Release version 0.20

Error behavior:

../jsonnet-lint/usr/bin/jsonnet-lint -J . test.libsonnet
test.libsonnet:10:1-10 Indexed object has no field "clamp"

std.clamp(0.5, 0.0, 1.0)


test.libsonnet:10:1-25 Called value must be a function, but it is assumed to be void

std.clamp(0.5, 0.0, 1.0)

Expected behavior: std.clamp in the above statement would lint cleanly.
