105 update to latest govuk frontend version

[sarahmwong]

Overview of changes

Update to 5.7.1 frontend - adding @cjrace as a reviewer as you've had experience updating this before too!

Everything looks ok apart from value boxes - tested this in master and still looks odd! I've raised #116 for Andy to revisit as this looks like a separate issue.

Removed some old manual changes from the css_changes.md file as no longer relevant

Not fully tested everything, but leaving the comments I have for now so they're not lost (as I'm not around tomorrow)

Spotted an issue with accordions (though not cross checked against main yet to see if it's pre-existing)

• Only the 'show' is clickable, if you click on the title of the accordion it doesn't open, though for GDS component it seems like clicking anywhere around the accordion title should also open it? https://design-system.service.gov.uk/components/accordion/

Do we use this anywhere? Looks like the footer crest, though seems odd we didn't already have a version of it? Do we need to point the footer function this this?

[cjrace]

Given we just copy this in now (and we are full rem instead of norem), would it make sense to change to leaving the name as the same as the one from the GOV.UK ZIP? I think then it's just a case of updating the attach function to import this sheet as a dependency?

[cjrace]

Was removing this font size a GDS or us change? I think a lot of the fonts all seem smaller now than they were?

Have finished my review now, there's only one other odd thing I've noticed (may or may not be related to the fonts comment)

Select input (dropdown) now cuts the bottom of text off
