Editor default configuration changed from ENTER_P to ENTER_BR on DXP 7.3 U-5

Issue

We found this commit on LPS-148819 witch changes the default value of ENTER_P (see #use-enter-mode-p) to ENTER_BR:
```
.put("enterMode", 2)
```
In U-22 ticket LPS-176361 has been used to revert it eliminating this property, so starting with this version it returns to the default value ENTER_P;
In order to solve this, you can choose one of this tree options:
- Update to at least DXP 7.3 U-22 in order to include this revert;
- Open a new ticket to support team and request a patch that includes LPS-176361;
- Write your own ConfigContributor changing this configuration to the default one (see Modifying an Editor's Configuration):
```
.put("enterMode", 1)
```
