VH 1314 - Allow V2X-Hub Web UI browser access without self signed cer…

…tificate warning acceptance (#622)

<!-- Thanks for the contribution, this is awesome. -->

# PR Details
## Description

In this PR, initialization script is updated to ignore the certificates
for localhost on google chrome and chromium browsers to remove the
manual step of navigating to websocket URL and accepting self signed
certificate. This will allow to access V2X-Hub Web UI without accepting
the risk in an other tab.

+### Access V2X-Hub 
+To access V2X-Hub UI, either chromium or google-chrome browser can be used by running the following commands:
+```
+chromium-browser --ignore-certificate-errors <v2xhub_ip>
+```
+or 
+
+```
+google-chrome --ignore-certificate-errors <v2xhub_ip>
+ ```
+
+> [!NOTE]  
+> V2X-Hub Server uses a secure WebSocket connection to communicate with the browser. For this, V2X-Hub Server uses a self-signed certificate instead of one signed by a trusted certificate authority (CA). Most of the browsers do not trust this until explicitly told to do so by navigating to the WebSocket URL (https://<v2xhub_ip>:19760) and accepting the risk. The `--ignore-certificate-errors` option instructs the browser to ignore certificate errors and warnings which removes manual effort of accepting this risk on V2X-Hub deployments. **Using the browser with this option enabled to access the internet or any other application is not advised as it is a security risk**.
