Updates the requirements on quote to permit the latest version.
Release notes
*Sourced from [quote's releases](https://github.com/dtolnay/quote/releases).*
> ## 1.0.0
> This release fixes some longstanding limitations of the `quote!` macro, bringing quote better in line with the patterns that macro authors are used to from working with macro\_rules.
>
>
>
> ## Duplicate interpolations in a repetition
>
> In past versions of quote, interpolating the same variable multiple times inside of one repeating block was not allowed.
>
> For example if we had an iterator of local variable names and wanted the generated code to do a clone of each one, that wouldn't compile:
>
> ```console
> error[E0416]: identifier `var` is bound more than once in the same pattern
> --> src/main.rs:7:27
> |
> 7 | #( let #var = #var.clone(); )*
> | ^^^ used in a pattern more than once
> ```
>
> Macros usually worked around this by having the same sequence of interpolated values named two different things:
>
> ```rust
> // old workaround 1
> let var = input.fields.iter().map(|field| &field.ident);
> let var2 = var.clone();
>
> quote! {
> #( let #var = #var2.clone(); )*
> }
> ```
>
> or by giving up on repetitions and doing more of the work within the iterator chain:
>
> ```rust
> // old workaround 2
> let var_clones = input
> .fields
> .iter()
> .map(|field| {
> let var = &field.ident;
> quote! {
> let #var = #var.clone();
> }
> });
>
> quote! {
> #(#var_clones)*
> }
> ```
>
