compiler: fix duplicated "the" in two doc-comments

Two one-line typo fixes for duplicated "the" in compiler doc-comments:
- `compiler/rustc_type_ir/src/solve/mod.rs` — "only if any of the the opaques in the opaque type storage has a hidden type" → "...any of the opaques in..."
- `compiler/rustc_borrowck/src/diagnostics/var_name.rs` — "/// Find the the name and span of the variable corresponding to the given region." → "/// Find the name and span of the variable corresponding to the given region."

No code/behavior change.
