feat: use defaultInfuraNetworks as default networks list

[mikesposito]

Explanation

Some new Infura network have been added to InfuraNetworkType (#8680), but NetworkController uses the same list of networks to:

• Build the default list of networks when creating the initial default state
• Validate new Infura networks being enabled

This has been fine until now because additional networks that can be enabled by users were added as "custom" networks. However, with the addition of new Infura networks, we have some networks that can be enabled by users but are not included in the default list of networks. This causes validation to fail when users try to enable those networks (via the Additional Networks list).

Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've communicated my changes to consumers by updating changelogs for packages I've changed
• I've introduced breaking changes in this PR and have prepared draft pull requests for clients and consumer packages to resolve them

Note

Medium Risk
Changes the set of networks that are auto-included on initialization, which is a breaking behavioral change that can affect users’ ability to switch to previously-default networks without first adding configurations.

Overview
Introduces DEFAULT_INFURA_NETWORKS (a curated subset of InfuraNetworkType) in @metamask/controller-utils and exports it for consumers.

Updates NetworkController to build its default networkConfigurationsByChainId from DEFAULT_INFURA_NETWORKS instead of Object.values(InfuraNetworkType), effectively removing Sei, MegaETH, Avalanche, and ZKSync from the default network set while keeping them available as Infura-supported networks.

Adjusts controller-utils export snapshots and network-controller tests/changelogs to reflect the new default-network behavior (breaking).

Nit: Should we use the standard name for constants?

Suggested change

	export const defaultInfuraNetworks: InfuraNetworkType[] = [
	InfuraNetworkType.mainnet,
	InfuraNetworkType.goerli,
	InfuraNetworkType.sepolia,
	InfuraNetworkType['linea-goerli'],
	InfuraNetworkType['linea-sepolia'],
	InfuraNetworkType['linea-mainnet'],
	InfuraNetworkType['base-mainnet'],
	InfuraNetworkType['arbitrum-mainnet'],
	InfuraNetworkType['bsc-mainnet'],
	InfuraNetworkType['optimism-mainnet'],
	InfuraNetworkType['polygon-mainnet'],
	InfuraNetworkType['monad-mainnet'],
	];
	export const DEFAULT_INFURA_NETWORKS: InfuraNetworkType[] = [
	InfuraNetworkType.mainnet,
	InfuraNetworkType.goerli,
	InfuraNetworkType.sepolia,
	InfuraNetworkType['linea-goerli'],
	InfuraNetworkType['linea-sepolia'],
	InfuraNetworkType['linea-mainnet'],
	InfuraNetworkType['base-mainnet'],
	InfuraNetworkType['arbitrum-mainnet'],
	InfuraNetworkType['bsc-mainnet'],
	InfuraNetworkType['optimism-mainnet'],
	InfuraNetworkType['polygon-mainnet'],
	InfuraNetworkType['monad-mainnet'],
	];

Alternatively should we narrow the type?
