Unsupported MIME type: application/x-sh fails with AWS Bedrock provider
Describe the bug
When using Goose with AWS Bedrock I often get this error when it supplies a Shell script to the LLM:
Ran into this error: Server error: Failed to call Bedrock: ValidationException(ValidationException { message: Some("Unsupported MIME type: application/x-sh. Re
try your request with a supported file type: xlsx, txt, pdf, csv, md, doc, html, xls, docx"), meta: ErrorMetadata { code: Some("ValidationException"), message:
Some("Unsupported MIME type: application/x-sh. Retry your request with a supported file type: xlsx, txt, pdf, csv, md, doc, html, xls, docx"), extras: Some({"
aws_request_id": "633ffad4-00b5-4282-9c07-dffa2678c50d"}) } }).
To Reproduce Steps to reproduce the behavior:
mkdir /tmp/test
cd /tmp/test
echo '#!/bin/bash
echo hi' > test.sh
goose run --text 'Summarize test.sh'
starting session | provider: bedrock model: us.anthropic.claude-3-7-sonnet-20250219-v1:0

I'll summarize the test.sh file for you. First, let me check if this file exists and then view its contents.
─── shell | developer ──────────────────────────
command: ls -l test.sh
-rw-r--r-- 1 wheel 20 Mar 4 14:37 test.sh
Let me view the contents of the test.sh file:
─── text_editor | developer ──────────────────────────
path: /private/tmp/test/test.sh
command: view
### /private/tmp/test/test.sh
``bash
#!/bin/bash
echo hi
``

Please retry if you think this is a transient or recoverable error.

It looks as though this might be coming from here: https://github.com/block/goose/blob/7b767abfe60979e4d623da292b6ba4354b8ef8af/crates/goose/src/providers/formats/bedrock.rs#L170-L171
From the docs:
Valid Values: pdf | csv | doc | docx | xls | xlsx | html | txt | md
I think Goose maybe sending "text" instead of "txt": https://github.com/block/goose/blob/1c2332cc685225f4d0f5decf15590169467d6170/crates/mcp-core/src/resource.rs#L47
Additional context N/A
Only been using Goose a few days and experienced this issue, but not specifically processing a .sh file. In my case I have an AWS CDK Project in TypeScript. The entry point file created by cdk init is /bin/somename.ts and Goose was chocking on this file with the "Unsupported MIME type: application/x-sh" error. Since I don't execute CDK TypeScript from the command line by running it directly, I simply dropped the shebang at the top of the file (#!/usr/bin/env node) and was able to get past the error.
👋 Apologies on taking so long to triage this. I'm able to recreate this error and it looks like Bedrock is doing some additional validation on their end for Documents to match/infer doc types, which is a bit annoying. I'm putting together a fix where if the doc type is not supprted, we'll just pass the the text content through as Text content rather than Document. PR incoming!
this is fixed in the latest canary on main. will be included in the next release
