fix(wordlist): Removed redundant linejumps from CommonAdminBase64.txt

[ItsIgnacioPortal]

Purpose of pull request

base64 strings in the 1st part of the list are built from strings without appended newline e.g. https://www.base64decode.org/dec/cm9vdA==

But the 2nd part strings got encoded wrongly with appending newline e.g. https://www.base64decode.org/dec/Um9vdDpSb290Cg==

I corrected all initial strings with awk trick so base64-ed strings have no newline encoded:
echo Root:Root | awk '{printf $1}' | base64
