doc(third-party-tools): remove instabug

[erisu]

Platforms affected

n/a

Motivation and Context

Remove third-party tools that appears to no longer support Cordova

Description

Instabug has been rebranded to Luciq.

It appears the Luciq website does reference any support or integration guides for Cordova.

Only one page in the docs says Cordova but the link takes you to a "Page Not Found".

Additionally, the instabug-cordova npm package also mentioned the following:

Support for Cordova will officially end on June 30, 2025.
