Subject: [PATCH] Bump repo (#128)

## Type of change

<!--Delete points that do not apply-->

- Improvement (refactoring, restructuring repository, cleaning tech
debt, ...)

## Changes

The following changes have been made:

- Bumped Libs to forc v0.37.0
- Bumped Standards to forc v0.37.0
- Bumped Tests to forc v0.37.0
- Bumped Contributing Book to forc v0.37.0
- Bumped CI to forc v0.37.0
- Bumped CI to rust v1.68.2

## Notes

- Please note the restructuring that has occurred due to the
implementation of `mod` over `dep`, specifically in the NFT and
Ownership libraries.
- Due to https://github.com/FuelLabs/sway/issues/4408 portions of the
tests for the String library have been commented out.

## Related Issues

<!--Delete everything after the "#" symbol and replace it with a number.
No spaces between hash and number-->

Closes #127

 The `append()` function currently causes an internal compiler error when used. It has been commented out until https://github.com/FuelLabs/sway/issues/4158 is resolved.
 
+
+Until https://github.com/FuelLabs/sway/issues/4158 is resolved, developers must directly access the underlying `Bytes` type to make modifications to the `String` type.
+
 It is important to note that unlike Rust's `String`, this `String` library does **not** guarantee a valid UTF-8 string. The `String` currently behaves only as a `vec` and does not perform any validation. This intended to be supported in the future with the introduction of [`char`](https://github.com/FuelLabs/sway/issues/2937) to the Sway language.
