Make search bar in dashboard have a more clear message.

[ze]

The current search bar in the users dashboard isn't very clear on what its functionality exactly is. The user can assume that it will search inside their projects or some other functionality.

This pull request allows for the search bar to have a more clear functionality.

Update: I should have provided an image to accompany this PR.

This is the search on the project scope

So, shouldn't it say Search in Read the Docs? (I'm not sure if that it's right wording)

My rationale was that since it has the same functionality as the search box at readthedocs.org
it would be appropriate if it had the same placeholder.

There are a lot of possible choices that can be defended, but this choice made the most sense to me.

I would even propose that we adjust that image you provided by further inspection
(inconsistent coloring with other tabs, semicolon is inconsistent as well, size is an h2 but all other tabs use an h1, etc).

Yeah, you are right! Do you want to open a new issue for the other suggested changes?

[ze]

I'll open one right now, thanks for reviewing my pull request!

Please make the string translatable

Alright, it's been done!
