fix: Add space after `xmlns:wsu` to prevent xmldom warning

[scagood]

This removes the following xmldom warning:

[xmldom warning]        attribute space is required"xmlns:wsu"!!
  at DOMHandler.warning (<root>/node_modules/@xmldom/xmldom/lib/dom-parser.js:251:29)

This was because there was no space between the following attributes in the Security header:

<wsse:Security xmlns:wsu="docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"soap:mustUnderstand="1">

This is now:

<wsse:Security xmlns:wsu="docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" soap:mustUnderstand="1">

🤔 I am not sure why the tests are failing, they look unrelated to the change I made.

The tests also look to be passing on my local machine 👀

The required fix can be found in #1206 I will rebase once that is merged.

I don't see any problem with this change, tried locally and all tests passed.
