perf: Drop use of Into::into for '?'

For binary size, this only dropped 0.2 KiB

For performance, before:
- parse_rustup_with_sc    time:   [7.9866 µs 8.0138 µs 8.0470 µs]
After:
- parse_rustup_with_sc    time:   [7.5387 µs 7.5722 µs 7.6157 µs]

For build-time, before
```console
$ hyperfine --warmup=1 --min-runs=5 "--prepare=cargo clean" "cargo build -F cargo --example cargo-example"
Benchmark 1: cargo build -F cargo --example cargo-example
  Time (mean ± σ):     16.988 s ±  1.190 s    [User: 68.178 s, System: 6.637 s]
  Range (min … max):   15.550 s … 18.277 s    5 runs
```
After:
```console
