Readme: Remove custom GeoSite/GeoIP DAT section

Remove the "Custom GeoSite / GeoIP DAT" section from the main README and all localized READMEs (ar_EG, es_ES, fa_IR, ru_RU, zh_CN). Also apply minor formatting cleanups: normalize language header spacing and remove trailing spaces from the Stargazers badge lines.

-## Custom GeoSite / GeoIP DAT sources
-
-Administrators can add custom GeoSite and GeoIP `.dat` files from URLs in the panel (same workflow as updating built-in geofiles). Files are stored under the same directory as the Xray binary (`XUI_BIN_FOLDER`, default `bin/`) with deterministic names: `geosite_&lt;alias&gt;.dat` and `geoip_&lt;alias&gt;.dat`.
-
-**Routing:** Xray resolves extra lists using the `ext:` form, for example `ext:geosite_myalias.dat:tag` or `ext:geoip_myalias.dat:tag`, where `tag` is a list name inside that DAT file (same pattern as built-in regional files such as `ext:geoip_IR.dat:ir`).
-
-**Reserved aliases:** Only for deciding whether a name is reserved, the panel compares a normalized form of the alias (`strings.ToLower`, `-` → `_`). User-entered aliases and generated file names are not rewritten in the database; they must still match `^[a-z0-9_-]+$`. For example, `geoip-ir` and `geoip_ir` collide with the same reserved entry.
