Use the text_reference table

[samjam48]

Currently, all the text on the website is hardcoded if it isn't related to a project in the airtable. We should use the text_reference table in airtable to make the content in the website dynamic so Generation Change can update it.

• Set up netlify call to airtable for any text that might want to be changeable (page titles, error messages etc...)
• Use the airtable data instead of hardcoded words

(in future this would also mean our site could be adapted for languages. e.g. if user is in France use the text_reference_FR table...)
