add margin above Remember Me for social login

Closes #35178

See merge request !12957

RE2 differs from Ruby in handling multiple-line strings. The string "foo\n"
will not match the regular expression "foo$" unless multi-line mode is enabled
(and it's off by default).

Since we're already scanning the build trace line by line (and so multi-line
coverage regular expressions won't work), we can fix this by removing the line
separator before scanning the string.
