update mpl-token-metadata dependency

hey @aheckmann We want to update this dependency since other projects, like Solana's explorer, use this SDK to read that library. This will allow the explorer to display the new token metadata standard in their metadata tab.

CI fails with The lockfile would have been modified by this install, which is explicitly forbidden.
We ran into this issue separately, yesterday. What worked for us was removing the current yarn.lock and reinstalling. Another action which may help is removing unrelated yarn.lock file in the home ~ directory and rerunning the above step. I'll open a new PR and see if this resolves it. (not sure if this is a yarn 3 issue or not yet)

Closing this one in favor of #168 which has passing CI
