docs: fix stale redirect links in four docs pages (#25738)

Four pages contained absolute `coder.com/docs` links that issued 308
redirects, creating unnecessary extra hops for readers. These were
identified via a SiteOne Crawler redirect-chain audit (DOCS-216).

| File | Old link | Final destination |
| -- | -- | -- |
| `admin/security/0001_user_apikeys_invalidation.md` |
`/docs/admin/audit-logs` | `/docs/admin/security/audit-logs` |
| `admin/templates/extending-templates/web-ides.md` |
`/docs/code-server/` (trailing slash) | `/docs/code-server` |
| `user-guides/workspace-access/index.md` | `/docs/code-server/latest` |
`/docs/code-server` |
| `install/cloud/azure-vm.md` | `/docs/coder-oss/latest/install` |
`/docs/install` |

Also quotes the `[install.sh]` bash associative array key in
`scripts/release/check_commit_metadata.sh` to fix a pre-existing shfmt
parse warning (shfmt misreads `.sh` inside unquoted `[...]` as a
floating-point expression).
