Remove %n in front and back of string

[jmslbam]

So if RECIPIENT or ORGANIZATION are not filled or empty, then this results in only a STREET_ADDRESS that's prefix with an %n which will be replace by a <br> which results in an address that's starts a line lower then needed.

Fixes #23

Thanks for your PR!

It looks like the tests are now failing. Would you mind updating them please?

[jmslbam]

@adamlc, Ah yes I see that now. As it's not related to the scope of this issue, shall I update them in a different branch so those can be merged first before proceding with this PR's.

The following actions use a deprecated Node.js version and will be forced to run on node20: actions/checkout@v3, actions/cache@v3. For more info: https://github.blog/changelog/2024-03-07-github-actions-all-actions-will-run-on-node20-instead-of-node16-by-default/

Looks like we be needing actions/checkout@v4.

I'll be honest I haven't used this library or php for years, but it looks like the unit test is actually broken.

The final n is being trimmed off the address, which could mean that it is related to this change.
