A typo in FpWeb.HostApp.Simple.pp: missing extension in included file name
[FpWeb.HostApp.Simple.pp](packages/fcl-web/namespaced/FpWeb.HostApp.Simple.pp) file contains a typo.
Currently it has the following contents:
```pascal
{$DEFINE FPC_DOTTEDUNITS}
unit FpWeb.HostApp.Simple;
{$i fpsimpleserver}
```
Note missing `.pp` extension in included file name. It causes Lazarus Codetools tests to fail with latest FPC 3.3.1.
I propose to change this file the following way similar to other files of this package:
```pascal
unit FpWeb.HostApp.Simple;
{$DEFINE FPC_DOTTEDUNITS}
{$i fpsimpleserver.pp}
```
