Fix Keplr link to proposal

[hakuno2000]

I suggest you should change Keplr url format in pkg/types/chain.go like below

	if c.KeplrName != "" {
		links = append(links, Link{
			Name: "Keplr",
			Href: fmt.Sprintf("https://wallet.keplr.app/chains/%s/proposals/%s", c.KeplrName, proposalID),
		})
	}

For example, it should be
https://wallet.keplr.app/chains/injective/proposals/418
instead of
https://wallet.keplr.app/#/injective/governance?detailId=418

Actually yeah, that makes sense. Do you mind making a PR updating it to the correct one?
(I can also do it myself, but I have a bunch of things I should do before that, so it might take some time.

Okay I merged it and pushed v5.14.1 release which should contain it.
Also tested it manually, seems to work correctly.

@hakuno2000 thanks for your contribution!
I'll close this one as resolved, feel free to reopen if you think it's not working correctly, of file a new issue if there's something else.
