fix: msrv in workspace

[roeap]

Description

Our min required rust version does not match the features we are using. Specifically, we are using impl Trait as a return type in a trait, which is only available since 1.75.

delta-rs/crates/core/src/delta_datafusion/mod.rs

Lines 238 to 241 in 8eb2b8b

	pub(crate) trait DataFusionFileMixins {
	/// Iterate over all files in the log matching a predicate
	fn files_matching_predicate(&self, filters: &[Expr]) -> DeltaResult<impl Iterator<Item = Add>>;
	}
