ldap: default domain name (#3414)

When the ldap synchronizer is look for an email address and fails at
finding one, it falls back at creating one using "localhost.local"
domain.

This new field makes this domain name configurable.

 * **Regressions and workarounds:**
   * Running the [`forgejo doctor check --fix`](https://forgejo.org/docs/v7.0/admin/command-line/#doctor-check) CLI command or setting [`[cron.gc_lfs].ENABLED=true`](https://forgejo.org/docs/v7.0/admin/config-cheat-sheet/#cron---garbage-collect-lfs-pointers-in-repositories-crongc_lfs) (the default is `false`) will corrupt the LFS storage. The workaround is to not run the doctor CLI command and disable the `cron.gc_lfs`. This regression will be [fixed in 7.0.1](https://codeberg.org/forgejo/forgejo/issues/3438).
-  * The [`fogejo admin user create`](https://forgejo.org/docs/v7.0/admin/command-line/#admin-user-create) CLI command [requires a password](https://codeberg.org/forgejo/forgejo/commit/b122c6ef8b9254120432aed373cbe075331132ac) change by default when creating the first user and the `--admin` flag is not specified. The `--must-change-password=false` argument must be given to not require a password change. This regression will be [fixed in 7.0.1](https://codeberg.org/forgejo/forgejo/issues/3399).
+  * The [`forgejo admin user create`](https://forgejo.org/docs/v7.0/admin/command-line/#admin-user-create) CLI command [requires a password](https://codeberg.org/forgejo/forgejo/commit/b122c6ef8b9254120432aed373cbe075331132ac) change by default when creating the first user and the `--admin` flag is not specified. The `--must-change-password=false` argument must be given to not require a password change. This regression will be [fixed in 7.0.1](https://codeberg.org/forgejo/forgejo/issues/3399).
 * **Breaking changes requiring manual intervention:**
   * [MySQL 8.0 or PostgreSQL 12](https://codeberg.org/forgejo/forgejo/commit/e94f9fcafdcf284561e7fb33f60156a69c4ad6a5) are the minimum supported versions. The database must be migrated before upgrading. The requirements regarding SQLite did not change.
   * The `per_page` parameter is [no longer a synonym for `limit`](https://codeberg.org/forgejo/forgejo/commit/0aab2d38a7d91bc8caff332e452364468ce52d9a) in the [/repos/{owner}/{repo}/releases](https://code.forgejo.org/api/swagger/#/repository/repoListReleases) API endpoint.
