chore: Fix typo in error message

[wzrdo]

Description

I noticed a typo in the error message where "atleast" was written as one word. This corrects it to "at least" for better readability and accuracy.

---

Here’s the corrected code snippet:

let &tip_height = latest_blocks
    .keys()
    .last()
    .expect("must have at least one entry");

Hey @wzrdo,

It's great that you're trying to contribute to the BDK project! However, I don't think this typo fix is substantial enough to be merged at this time. I recommend checking out issue #1762 and the contributing guide. Addressing multiple typos in a single pull request or resolving issues with more substance, like fixing bugs or adding new features, would provide more value and increase the likelihood of your pull request being accepted.

And I think that's quite enough. I've looked at the pull request history, you've even accepted a single corrected letter, so go ahead, get to work!
