doUpdate argument is an array not string

[kayvaninvemo]

In the document there is an example as follow:

.onConflict('name').doUpdate('age')

but actually it should be:

.onConflict('name').doUpdate(['age'])

do I miss a thing?

Can make both work, I guess. Do you want to create a PR? Also lacking tests here :(.

I took a look at the code. Actually the code is more complicated for my limited time to understand and fix. But I can fix the example in Documentation.
