This is more in line with how we handle closely coupled specifications
already. While there are subdirectories for "large" specifications (such
as MUC and PubSub), those only refer to a single XEP document. When
there are multiple separate XEP documents, we have separate modules for
that.
There is at least one branch of the FromStr implementation which passes
user input right into the error struct, so we cannot assume that `'` is
not part of that value.
The previous code didn't build with 1.78:
```
error[E0716]: temporary value dropped while borrowed
--> parsers/src/data_forms/validate.rs:394:46

380 | let value = match self {
| ----- borrow later stored here
...
394 | Datatype::UserDefined(value) => &format!("x:{value}"),
| ^^^^^^^^^^^^^^^^^^^-

| | temporary value is freed at the end of this statement
| creates a temporary value which is freed while still in use
|
= note: consider using a `let` binding to create a longer lived value
= note: this error originates in the macro `format` (in Nightly builds, run with -Z macro-backtrace for more info)

```
This seems like a silly reason to pull up the compiler version
requirements, so I fixed it with a trivial modification.
