dev: SWIS endpoint changing to TCP/17774

Solarwinds is changing the port for the SWIS API to 17774. 17778 works for now, but is deprecated.

See [2023.1 release notes](https://documentation.solarwinds.com/en/success_center/orionplatform/content/release_notes/solarwinds_platform_2023-1_release_notes.htm)

Easy enough to change in the script as it is, but figured I would mention it.
