Rollup merge of rust-lang#140564 - ebkalderon:use-present-indicative-in-std-io-pipe-docs, r=tgross35

Use present indicative tense in std::io::pipe() API docs

The inline documentation for all other free functions in the `std::io` module use the phrase "creates a" instead of "create a", except for the currently nightly-only `std::io::pipe()` function. This commit updates the text to align with the predominant wording in the `std::io` module.

I recognize this PR is quite a minuscule nitpick, so feel free to ignore and close if you disagree and/or there are bigger fish to fry. Thanks in advance! :smile:

Relates to rust-lang#127154.
