Regex does not support in lookup

[foesa-yang]

In Nebula Graph version v2.5.0, the following statement is not supported:

(root@nebula) [basketballplayer]> LOOKUP ON player WHERE player.name =~ "^.{15,20}$" YIELD player.name, player.age;
[ERROR (-1009)]: SemanticError: Expression (player.name=~"^.{15,20}$") not supported yet

But in the previous version, the statement has a return value as follows:

nebula> LOOKUP ON player WHERE player.name =~ "^.{15,20}$" \
        YIELD player.name, player.age;
+-------------+----------------------+------------+
| VertexID    | player.name          | player.age |
+-------------+----------------------+------------+
| "player147" | "Amar'e Stoudemire"  | 36         |
+-------------+----------------------+------------+
| "player144" | "Shaquille O'Neal"   | 47         |
+-------------+----------------------+------------+

this is not about full-text-index. it's about lookup for strings.

This case has been tested here. It seems this PR wasn't cherry-picked. I'll check the source code.

I have confirmed that this pr is not picked into the v2.5.0 release.

[CPWstatic]

I test it in v2.0.0, it also not works. Please confirm if we had support this feature in any of our early versions.
