build(deps): bump github.com/open-policy-agent/opa from 0.47.4 to 0.48.0

[dependabot]

Bumps github.com/open-policy-agent/opa from 0.47.4 to 0.48.0.

Release notes

Sourced from github.com/open-policy-agent/opa's releases.

v0.48.0

This release rolls in security fixes from recent patch releases, along with a number of bugfixes, and a new builtin function.

Improved error reporting available in opa eval

A common frustration when writing policies in OPA is when an error happens, causing a rule to unexpectedly return undefined. Using --strict-builtin-errors would allow finding the first error encountered during evaluation, but terminates execution immediately.

To improve the debugging experience, it is now possible to display all of the errors encountered during normal evaluation of a policy, via the new --show-builtin-errors option.

Consider the following error-filled policy, multi-error.rego:

package play
this_errors(number) := result {
result := number / 0
}
this_errors_too(number) := result {
result := number / 0
}
res1 := this_errors(1)
res2 := this_errors_too(1)

Using --strict-builtin-errors, we would only see the first divide by zero error:

opa eval --strict-builtin-errors -d multi-error.rego data.play

1 error occurred: multi-error.rego:4: eval_builtin_error: div: divide by zero

Using --show-builtin-errors shows both divide by zero issues though:

opa eval --show-builtin-errors -d multi-error.rego data.play -f pretty

2 errors occurred:
multi-error.rego:4: eval_builtin_error: div: divide by zero
multi-error.rego:8: eval_builtin_error: div: divide by zero

By showing more errors up front, we hope this will improve the overall policy writing experience.

New Built-in Function: time.format

It is now possible to format a time value from nanoseconds to a formatted timestamp string via a built-in function. The builtin accepts 3 argument formats, each allowing for different options:
