Enabling Keplr, support for multiple currencies when connecting Keplr wallet bugs

[avendauz]

Encountered a few bugs when trying to connect a wallet via Keplr:

• When trying to enable Keplr, an experimentalSuggestChain config is generated referencing the chain to be added to Keplr. The window allows a user to edit the config, but none of the changes persist when approving the chain in the popup in Keplr.

• The experimentalSuggestChain config that is generated by ping-pub only supports one currency/asset, even if multiple assets exist on that chain (see explorer/src/chains/mainnet/stafihub.json, which has 4 different assets). Manual testing suggests that only the first asset of the array of assets of the json config are used in the experimentalSuggestChain config.

Hey, I think you can edit the config json in the text box before enable.

"currencies": [
		{
			"coinDenom": "CRE",
			"coinMinimalDenom": "ucre",
			"coinDecimals": 6,
			"coinGeckoId": "crescent-network"
		},
        // you might need add those assets here.
