Here is the code for @zzpaul comment above

<referenceBlock name="page.main.title"> <arguments> <argument name="title" xsi:type="string" translate="true">Forgot Your Password</argument> </arguments> </referenceBlock> 

Just use it in your custom customer_account_forgotpassword.xml

From Devdocs :

The <action> instruction is deprecated. If the method implementation allows, use the <argument> for <block> or <referenceBlock> to access the block public API.

It still does not seem possible to set a title in the head section and translate it, but you could create a custom customer_account_forgotpassword.xml to fix the issue with this code

<referenceBlock name="page.main.title"> <arguments> <argument name="title" xsi:type="string" translate="true">Forgot Your Password</argument> </arguments> </referenceBlock>
