[SECURITY] Fedora 40 Update: icecat-115.8.0-2.rh1.fc40

GNU IceCat is the GNU version of the Firefox ESR browser. Extensions included to this version of IceCat: * LibreJS GNU LibreJS aims to address the JavaScript problem described in the article “The JavaScript Trap” of Richard Stallman. * JShelter: Mitigates potential threats from JavaScript, including fingerpri nting, tracking, and data collection. Slightly modifies the results of API calls, differently on different domains, so that the cross-site fingerprint is not stable. Applies security counter-measures that are likely not to break web pages. Allows fine-grained control over the restrictions and counter-measures app lied to each domain. * A set of companion extensions for LibreJS by Nathan Nichols are pre-installed, and provide workarounds to use some services at USPS, RSF.org, SumOfUs.org, pay.gov, McDonalds, goteo.org and Google Docs without using nonfree JavaScript. * A series of configuration changes and tweaks were applied to ensure that IceCat does not initiate network connections that the user has not explici tly requested. This implies not downloading feeds, updates, blacklists or any other similar data needed during startup.
