chore(governance): fill the template tokens that have a factual answer (#79)

The template tokens in these files had a factual answer, so they are
filled:

- `.github/SECURITY.md`
- `.github/CODE_OF_CONDUCT.md`

**Left deliberately for the owner** — these ask for values a machine
must not invent (a wrong security contact is worse than an
obviously-unfilled one):

- `.github/SECURITY.md`: `{{PGP_FINGERPRINT}}`, `{{PGP_KEY_URL}}`,
`{{PLACEHOLDER}}`, `{{SECURITY_EMAIL}}`, `{{WEBSITE}}`
- `.github/CODE_OF_CONDUCT.md`: `{{CONDUCT_EMAIL}}`, `{{CONDUCT_TEAM}}`,
`{{PLACEHOLDER}}`, `{{RESPONSE_TIME}}`

Filling those is a one-off decision about estate contact details, not a
per-repo edit.
