Don't let those keys expire. 🚨

Time to edit some keys:

```shell
gpg --edit-key t@travisshears.com
Secret key is available.
sec  rsa2048/D4C2E4DFAB8BABF8
     created: 2018-07-18  expires: 2020-07-17  usage: SC
ssb  rsa2048/25C629D0FECC25B9
     created: 2018-07-18  expires: 2020-07-17  usage: E
ssb  rsa4096/97F7C2B46E6C5D11
     created: 2019-09-28  expires: 2023-09-28  usage: E
```

1. select key to change `key 1`
1. `expire`
1. duration: `1y`
1. repeat until every key is updated

resulting output should be something like:

```shell
sec  rsa2048/D4C2E4DFAB8BABF8
     created: 2018-07-18  expires: 2021-06-22  usage: SC
ssb  rsa2048/25C629D0FECC25B9
     created: 2018-07-18  expires: 2021-06-22  usage: E
ssb  rsa4096/97F7C2B46E6C5D11
     created: 2019-09-28  expires: 2021-06-22  usage: E
```

lastly `save` and done
