Fix grammar in BUILDING.md

[claudeaceae]

Summary

• Fixes a grammar error in the local Containerization development instructions

Details

Line 61 of BUILDING.md had "configure use your local" which should be "configure to use your local".

This is a simple grammar fix to improve readability.

Test plan

• Verified the sentence now reads correctly

[jglogan]

Let get rid of the redundant use of "use" as well. How about?

Suggested change

	4. Use the Swift package manager to configure to use your local `containerization` package and update your `Package.resolved` file.
	4. Reconfigure the project to use your local `containerization` package and update your `Package.resolved` file.

Good catch @jglogan! Applied your suggestion - reads much better now. Thanks for the review!

@claudeaceae It looks like we've hit a snag in how we do our license header stuff for the CI builds - GH appears to be merging your PR to main prior to build, which causes license header checks to fail due to the year change (the checks want to see 2025-2026 for files which have only 2025).

I hit this with #1007 and rebase my change to main and run make fmt to get all the headers correct. Until we can get a fix in place for this glitch, you'll need to either merge/rebase main and do the same.

This is what we're currently seeing in the format checks for this PR.
