Issue: Extract-i18n regression between angular 13 and 14 for some generated xliff messages
Labels: area: i18n

### Which @angular/* package(s) are the source of the bug?

compiler-cli, language-service, localize

### Is this a regression?

Yes

### Description

The extract-i18n command generates bad error source in the Xliff format in angular 14, but with same code it was OK with angular 13.


Here is an exemple
 - For the following HTML CODE
```
<mat-error  i18n="@@ERROR_TCP_PORT">
           The TCP port is between
            <strong>{{ PORTS_DEFAULT_VALUES.PORT_MIN }}</strong>
            and <strong>{{ PORTS_DEFAULT_VALUES.PORT_MAX }}</strong>
</mat-error> 
```


In angular 13, the extract-i18n command generates the following xliff entry wich was working well. We retrieve in the source the 2 interpolation values PORTS_DEFAULT_VALUES.PORT_MIN and PORTS_DEFAULT_VALUES.PORT_MAX


```
<trans-unit id="ERROR_TCP_PORT" datatype="html">
        <source> The TCP port is between 
             <x id="START_TAG_STRONG" ctype="x-strong" equiv-text="&lt;strong&gt;"/>
             <x id="INTERPOLATION" equiv-text="{{ PORTS_DEFAULT_VALUES.PORT_MIN }}"/>
              <x id="CLOSE_TAG_STRONG" ctype="x-strong" equiv-text="&lt;/strong&gt;"/> and 
              <x id="START_TAG_STRONG" ctype="x-strong" equiv-text="&lt;strong&gt;"/>
              <x id="INTERPOLATION_1" equiv-text="{{ PORTS_DEFAULT_VALUES.PORT_MAX }}"/>
              <x id="CLOSE_TAG_STRONG" ctype="x-strong" equiv-text="&lt;/strong&gt;"/>
     </source>
     ...
</trans-unit>
```

in angiular 14, the extract-i18n command generates the BAD following xliff entry. The 2 interpolation values are lost and replaced by strange values ES.PORT_MIN and ES.PORT_MAX

```
  <trans-unit id="ERROR_TCP_PORT" datatype="html">
        <source> The TCP port is between
                <x id="START_TAG_STRONG" ctype="x-strong" equiv-text="&lt;strong&gt;"/>
                <x id="INTERPOLATION" equiv-text="ES.PORT_MIN }}"/>
                <x id="CLOSE_TAG_STRONG" ctype="x-strong"/> and 
               <x id="START_TAG_STRONG" ctype="x-strong" equiv-text="&lt;strong&gt;"/>
               <x id="INTERPOLATION_1" equiv-text="ES.PORT_MAX }}"/>
              <x id="CLOSE_TAG_STRONG" ctype="x-strong"/>
        </source>
      ....
      </trans-unit>
```
