Changes

• Replace sigs yaml deps by go-yaml

@42atomys please take a look. Formatting change due to gofmt.

Worth noting that all tests are failing locally:

--- FAIL: TestMustToDate (0.00s)
    --- FAIL: TestMustToDate/TestDate (0.00s)
        conversion_functions_test.go:143:
            	Error Trace:	/Users/andig/htdocs/sprout/test_helpers_test.go:57
            	Error:      	Not equal:
            	            	expected: "time.Time-2024-05-09 00:00:00 +0000 UTC"
            	            	actual  : "time.Time-2024-05-09 00:00:00 +0200 CEST"

Seems that the tests are not stable regarding time zone? Makes it hard to pick up the actual errors.
