fix: replace deprecated trimRight() with trimEnd()

[tejgokani]

Description

The host getter in lib/request.js:427 uses the deprecated trimRight() method, which is an Annex B legacy alias for trimEnd().

Why This Matters

• trimRight() is deprecated and may emit warnings in future Node.js/V8 versions
• trimEnd() is the ES2019 standard equivalent with identical behavior
• This aligns with Express's modernization efforts

Changes

• Replaced .trimRight() with .trimEnd() in the host getter

Testing

• Existing tests pass (run npm test)
• No new tests needed (this is a 1:1 method replacement with identical behavior)

Closes #XXXX (only if linking to an existing issue)

trimEnd was added in Node.js 10.0.0, so this should be safe 👍

(trimRight have been available since at least Node.js 0.10)

[tejgokani]

okay so am i approved to merge?

[LinusU]

CI is green, but will wait for one other maintainer to look at it as well 🚀

[tejgokani]

Okay. Thanks for the quick response.

There is also #7047, which replaces .trimRight(), but also for some reason adds .split(). I think I planned asking the author why did they introduce .split(), but for some reason I did not do it.

If this is merged, then #7047 probably should be closed.

[tejgokani]

Great! I appreciate the consideration. I'd like to keep moving forward with my PR.

My focus is on a clean, focused fix: replacing the deprecated trimRight() with
trimEnd(). This is a straightforward modernization with minimal risk.

I noticed #7047 also addresses this but adds .split() which seems like a separate
concern. Once my PR merges, I'll personally investigate why .split() was added
and follow up with a separate issue/PR if needed.

This keeps the changes focused and reviewable: one fix per PR. I'm committed to
seeing this through and ensuring the .split() question gets answered.

Let me know if you'd like me to make any adjustments! 🙌
