fix(idl_gen_rust): Fix lifetime warning added in Rust 1.89 (#8709)

Browse Source 
Rust 1.89 added a new lifetime-related warning:
<https://blog.rust-lang.org/2025/08/07/Rust-1.89.0/#mismatched-lifetime-syntaxes-lint>

The Rust code generator currently emits code which trips this warning. This very small PR
fixes the issue for the relevant generated functions and for the Rust flexbuffers code.

Fixes #8705
