[chore] update go-structr and go-mangler to no longer rely on modern-go/reflect2 (#3026)

Browse source 
* updates go-structr and go-mangler to no longer rely on modern-go/reflect2 (*phew* now we're go1.23 safe)

* update go-structr version

* bump go-structr to improve memory usage (v. slightly) in certain conditions

[Documentation](https://pkg.go.dev/codeberg.org/gruf/go-mangler).
To put it simply is a bit of an odd library. It aims to provide incredibly fast, unique string outputs for all default supported input data types during a given runtime instance.
To put it simply is a bit of an odd library. It aims to provide incredibly fast, unique string outputs for all default supported input data types during a given runtime instance. See `mangler.String()`for supported types.
It is useful, for example, for use as part of larger abstractions involving hashmaps. That was my particular usecase anyways...
This package does make liberal use of the "unsafe" package.
Benchmarks are below. Those with missing values panicked during our set of benchmarks, usually a case of not handling nil values elegantly. Please note the more important thing to notice here is the relative difference in benchmark scores, the actual `ns/op`,`B/op`,`allocs/op` accounts for running through over 80 possible test cases, including some not-ideal situations.

The choice of libraries in the benchmark are just a selection of libraries that could be used in a similar manner to this one, i.e. serializing in some manner.
