My details - change password

[lauraroverts]

Test plan

GIVEN the 'My details' section in MyRSR
WHEN viewing this section
THEN the 'Change password' form should be shown on this page

Issue description

In My RSR, there is a separate section to change your password 'Change password'. It makes more sense to include that in My details.

Based on the wireframes of the new results framework backend, this functionality will remain on a separate page, but on a new location (in the top navigation):
